Mamiya M Autofocus – 35mm point and shoot camera

What the listing stated:

Mamiya M point and shoot camera. It’s in fantastic original condition and is cosmetically excellent with original case and lens cap included. The lens appears to be bright and clear from the front. 
HOWEVER…when batteries are inserted the shutter does not fire and I suspect it is jammed somewhere. The lights come on and it goes “click” but the aperture does not open, nor does the film winding do anything. 
For spares or repairs only, I’m sure somebody with the know how could get it up and running again. 
Priced super low as I want it shifted and can’t bring myself to bin it! 
No returns please

EBay

A well made 80s point and shoot 35mm camera

Here’s a little bit about it:

The Mamiya M is a 35mm autofocus compact from 1982.  It has a boxy plastic shape, with a fixed Mamiya Sekor 38mm f/2.8 lens.  The lens is four elements in three groups.  Exposure is fully automatic, based on the film speed, where the ISO is selected via a dial around the lens. Film speed available is 25 – 800 ISO.  

The metering cell is located just under the lens, but within the lens ring.  This allows for the metering to take into account any 46mm filter screwed onto the lens.  That is assuming it is not a graduated filter.  Fastest shutter speed is 1/500thsecond with the slowest at 1/8th.  The camera is always on, except when fitted with a specially designed lens cap, which triggers the off state.  There is a strategically placed switch it pushes against on the right side of the lens.  Most of these caps are lost, including mine.

Photothinking.com

I don’t know what attracted me to this camera, but the fact the seller just wanted rid of it at a cheap price was a starting point. It was advertised as £4:36 GBP and £2:45 delivery, a total of £6:81GBP. I bartered a bit and got it all in for £5:44GBP so I got it a little bit cheaper, a bargain if you like.

Mamiya has a great reputation for building high quality lenses. They were only in the 35mm autofocus point and shoot sector for a short while before immersing themselves totally into the medium format camera market. This 35mm camera was only in production for about a year or so, even though quite a few were produced, we are looking at the low hundreds of thousands, not the many millions, so the camera itself was not a major mass produced and marketed unit. It is a plastic preformed body unit. Known in polite society back in the day as “A plastic fantastic”.

If a Mamiya camera had a blue ring around the lens, specifically on its other models, it denoted a higher quality lens type, it was never confirmed this was the case with these small autofocus 35mm cameras, though many believe it is still the case. Photo quality with these little units was generally of a very high quality.

Lens caps with these cameras are very rare, this one has one and it is the original, and i suspect (from what I see in the picture) that there may be a small crack on the side of this one, but that is not an issue. This lens cap is integral to this cameras operation, as when it is placed over the lens, it turns off the camera, without it the camera remains live at all times, and would soon lose its power. It is an early power conserving device if you like. The camera looks to be in overall good condition, probably down to being stored in its original case.

You can view a lot more than I could ever tell you, just by watching this review by Mr.50mm that was posted earlier this year.

Excellent recent review

Since reading up a little on these cameras it appears that I may well have bagged a bargain, if it ever works. And I also believe the seller may well again be unaware of the operation of this camera and it may in fact be working just fine? Who knows? I have my suspicions but we will just have to wait until it gets here for assessment.

Below are some sale prices relative to this camera model that are currently selling on EBay, some extremely high prices compared to what I have paid today:

Current selling prices for this model

It’s plastic and so 80’s. And people obviously loved it. I’d like to be able to get this camera working again, and would love to run a roll of film through it to give it a test run. But first I have to assess it and see just what is wrong with it. I have a roll of old film available to test its “faulty” rewind system, and I have all my tools ready to crack it open and get inside, if I have to. So let’s get at it….

Assessment:

It’s arrived and I must say it is in an excellent cosmetic condition, probably down to being kept in its original Mamiya soft case. The lens cap I thought had a crack in, is actually broken, probably beyond reasonable repair, but at the moment that is not important. Let’s put that to one side for now.

Nice condition
Lens cover damage

The actual camera is partially alive. When batteries are installed there is a red light that appears on the right rear side of the camera, this is the film transport light and should extinguish when transport is complete. The flash switch sticks a little, and when the flash is clicked into position the distance sensor light on the lens activates however the flash does not charge. The winding system is inoperative and does not auto wind at all. The shutter does not operate, despite the shutter leaves being able to move when gently coaxed.

Shutter not firing
Transport light in top right corner
Focus light illuminates on front

There seems to be partial electricity throughout, this could very well be the issue. There just doesn’t seem to be a uniform continuity throughout the camera. This will need to be looked at. Something very weird is going on inside.

Repair:

I’m really annoyed, closer inspection shows there are 6 screws missing and someone has been inside this camera prior to me. Again I think I’ve been stung by the EBay curse of “Spares and repairs- no returns” will I ever learn?

I’ve removed the remaining screws, and had to peel off the rubber grip to access and expose the motor and associated component board in this area. There will need to be a lot of cleaning here before gluing it all back in place.

That glue
Motor exposed
The grip gently peeled away

I’ve managed to get the flash charging light illuminated, and a current of 214v in the flash confirms that the Flash capacitor is holding a charge and more importantly, receiving a charge from the battery circuit. But I cannot get it to fire. There seems to be an issue with the shutter mechanism and the related electrical circuit in this area. The motor is not working, it’s either dead or not receiving power. I need to look in this area a little more thoroughly.

Front fascia removed

I’ve now removed the front fascia and now have a good view of the overall workings inside the camera.

Flash circuit board- tested ok
Lens and leaf shutter removed

Ive taken out the lens and the leaf shutter, these seem ok and are working freely when operated. To me it looks as if the mechanism that triggers the leaf shutter is either seized or the variable capacitance system located at the top of the camera, that is basically just a needle on a circuit board connected to the focus light, could be at fault, it does not freely move on each camera actuation as it should, and this is not a readily available part.

That faulty part of the board
Misfiring- faulty

It seems the deeper I delve into this camera that I am finding more issues, and I’ve just found two parts that are incorrectly installed that are on a cog system connected to the motor. I’m fighting a losing battle as it appears the person who has been here before has probably added to the issues of this camera in their attempt to fix the original issue.

On top of the missing screws I’ve now found a missing capstan cog related to the leaf mechanism that would help explain a certain lack of movement in areas. The motor is dead, I’ve taken it out and used the bench power supply and it is non responsive. Even after spraying with some contact cleaning fluid and sitting there spinning the axis to get the solution absorbed, there is still no response. It’s totally dead and will require replacement.

Result:

Well. Once again I have been mislead by incorrect descriptions on the auction sites. It’s a shame really as this is a lovely camera and if it had not been tampered with inside, I’d probably be posting a different review today, one that would be more positive. With screws, cams and cogs missing I was pretty much set up to fail here.

Reassembled
Back in its case

I’ve reassembled the camera and it is now back in its pouch. The positives are that I have learned a lot about how this camera operates, and just dismantling and reassembling the camera allows you to learn a lot about it, and the technology used during that period in time. All the screws that I removed have gone back into place with none leftover, yet another positive.

So it’s a failure I’m afraid, but it will be kept and either used as spares or I will obtain a suitable donor to get this one up and running, it will not be disposed of in any way. It will be reused. I’ve only paid a small amount for this, it’s worth it for the spares alone.

I have already set up a notification on the auction sites for when another suitable camera becomes available. I will update this post or post a new one that incorporates either the repair of this unit or its use as a spare parts donor, when that time comes.

Thanks for passing by. Its appreciated.

Comes with front / rear lens caps

EBay

Anyone that has followed my recent repair of the camera: Fujifilm Finepix S2 Pro will be aware that I purchased a lens as a test lens for working on some stock that required a Nikon mount. I went cheap and purchased a lens that was so badly affected with lens fungus that it will require a deep clean and some TLC. Anyway, it allowed me to test electrical contacts and all the menus, and that was about it, it served a purpose there, but taking a picture was like looking into a deep fog, it was hopeless. Anyway that lens is now set aside and will become one of those projects to dig into on a long winter evening…or two, or three.

As I have a number of Nikon based cameras needing assessment on the horizon, some with sensor issues, i have made the decision to pay a little more for some quality, from a company called AP photographic who specialise in quality used equipment, a company that is based close to where i used to live down in the south. This Lens has cost me £58:95GBP including postage, a fair but good price for some peace of mind. This post will not be a repair post as there is nothing wrong with this lens, it will be more of an assessment of the lens when used with the Fuji S2 pro i featured in a previous post.


Nikon Nikkor 28-100mm Zoom Auto Focus Lens F3.5-5.6 

I’ve put this post up to show the difference in the pictures taken on the S2 with both the old lens as well as this lens. I think the results will show quite a noticeable contrast and confirm just how restrictive a lens is when it is infected with a fungus problem.

Assessment:

The lens has arrived

The lens arrived within a couple of days and is in perfect condition. It has a lens cap and bayonet cap so is perfectly protected against dust dirt and damage from foreign objects. And when the lens cover is removed there is another little surprise, a post it note saying “Filter is a free gift” that just happens to be attached to a daylight filter. Nice little touch 👌

Nice touch

Lens is a perfect fit, no aperture ring on it as it is fully automatic, full autofocus. I’m not sure how the flash will work with this lens though when I use the Fuji S2 Pro, as that body works best with a fully closed lens aperture, but I’m sure I’ll be able to work it all out and get it functioning as it should. And I did, i played with the Aperture settings in “A” mode and it works just fine. It’s faultless.

Attached to the Fuji S2 Pro

That said on the S2 it not only looks good, it takes good pictures. Compared to the lens I last used this one is crystal clear, not a bit of fungus no aberrations and not a speck of dirt. This is a good lens and will serve me well for the purpose of testing other equipment I have awaiting attention. I think I’ve purchased a good example here.

Result:

I can confirm that the Fuji S2 Pro does not have a thing wrong with it and is working perfectly. All modes, all conditions are performed just as they should be. This lens is gorgeous as it is so clear and has been so well looked after. I believe this whole unit will be the one I wander about with when i go out on my walks. I can’t wait to take some serious photos to post.

A quick comparison fungus lens v clear lens as seen on the camera LCD screen

I took some pictures just randomly around the home setting with the old lens to show how foggy things were with the lens fungus. I have tried to take some more photos of the same locations with the new lens as well to just show how they compare and these can be seen in the pictures grouped below.

Before and after pictures, what a difference the fungus has had on the results.

All these pictures are on an old CF card so it is a bit of a palaver to get them on to new technology, but it is doable, it just takes a little time, and this gadget allows me to load numerous card types even the CF cards direct to my iPhone via a lightning connector. It also has a USB-C connector for other phones. It works really well as you can see in all the pictures in this post.

Multiple media cards direct to my iPhone

And below are a few random photos taken on the S2, it has a good black and white mode but is quite heavy on contrast. Post editing would probably be recommended, but to be honest I really love its moody appearance.

4 random photos in and around the house. And Tabs the feral cat popped by

This camera and this lens have proved fantastic. I know you can get far superior picture sizes and quality on a basic mobile phone, but where the heck is the fun in that? This camera cost me £8:00GBP. Just £8:00. And it is a superb camera that will be going on many trips with me as I just love it and how it looks. I now know it intimately after reading up on it and testing it, and cannot wait to put that knowledge to use.

Cameras are better than mobile phones. Old ones like this are fun, and an absolute privilege to use. It’s not all about the Megapixels, just remember these old cameras were the ones taking high quality professional pictures back in their day. Just because time moves on, and just like an elderly old lady or gentleman, they should not be discarded because they no longer serve a purpose. Respect the older technology, learn from it and you will ultimately become a wiser person yourself. Oldies rule! Never forget it. 👊

Thank you so much for passing by. It’s always very much appreciated.

Fujifilm Finepix S8000fd

I’ve purchased three cameras as a job lot in an auction. All of them have issues but the issues have not been clarified. This is very much a “Suck it and see” auction where I get what I’m given. I’ve paid £24:22GBP for all three and that includes free postage. I’ve purchased from this seller before who is a bonafide Camera business based in South Wales. He has no time for faulty items though, quick in and out is his way of working, no time to fix stuff. I’ve got three good cameras in this bundle and this works out at just about £8:00GBP per camera. And where can you get cameras like this for those prices nowadays.

I really don’t know what the specific issues are with this camera, only that it appears to have the mode selector dial missing from its top. I guess we will just have to wait it’s arrival for a full assessment. In the meantime here is a little bit about it.

With the release of the FinePix S8000fd, Fujifilm brings to market a smart-looking digicam with an 8-megapixel imager, one of the longest zoom lenses in the market plus a compact, and relatively light, camera body. The cheapest of three similarly featured long zoom cameras in the current market (see table below for a feature comparison), the S8000fd has the distinction of being able to use both xD-Picture Card and SD cards (including SHDC), which are fitted in a single dual-format slot. Release date July 2007.

Photo review newsletter

Assessment:

Well, to be honest, for potentially the worst camera in the box of the three that were purchased, it works just fine. Apart from that missing mode selector dial on the top of the camera. You have to use a pair of tweezers to get each mode to appear, but they are all there and the zoom and flash all work and it takes pictures fine, just as it should.

Tidy unit – working
Flash operates
All menus available
Mode dial – missing

Apart from the issue with the dial, all that is really needed is a little clean up, and even that isn’t that bad.

It does not justify being used as spares and is far too good to just be disposed of. I’m going to try and repair this.

What a bonus!

A little bonus was that there was a 1Gb SD card in the memory slot that works. There were also 4 rechargeable batteries in the camera that after a while on my charger, have fully recharged, and this makes the deal an even better one and quite a bargain to be honest with you.

Repair:

I’ve tested all systems, menus and functions on this camera and there really is nothing else wrong with it. It’s far too good to be used as a spares camera and deserves to be repaired.

Missing mode selector dial

I have two options here, either buy the mode selector dial on its own from our friends in China, or buy another donor camera in a far worse state and available for about the same price as getting the dial from China. I just have to wait for that donor camera to first become available. I’ll give it a couple of weeks and if nothing comes up then China it is.

In preparation for whatever route I decide to take, I’ve decided to do some prep on the old camera and get the old selector dial mechanism taken out ready for the new dial to be put in place.

I’ve dismantled the camera unit to be able to access what is left of the mode dial switch.

Back is off
Switch unit and ribbon cable
Switch removed
It’s basically a two piece potentiometer type setup

This wasn’t too awkward to dismantle, half a dozen screws and a small plastic prise tool was all that was required to reach this point. There was some protectorate covering the metal frame of the switch housing that was contained by four tiny screws. Once this was loosened the housing came away and I was able to remove what was left of the old mode dial that had originally been in place. There wasn’t a lot left.

Remains of previous dial

The camera now sits in this position of being dismantled whilst I source a new dial to replace. As stated I have two options of buying a new dial either from China, or by getting a damaged camera as a spares source, and I’m currently looking at the latter as this could be purchased for about the same price as the dial from China, and would allow me a few more spares.

I’ve purchased another unit as a donor. The unit in question has a damaged LCD screen. I’m going to use that camera as a donor for the mode dial I require.

The donor camera has arrived. And to be honest it looks ok. It has been dropped at some time as the lens has a scratch on it, and the Rear LCD screen is damaged. That’s about it.

A good looking donor camera, the only issue being the damaged LCD screen

I’ve taken some pictures with this unit and the camera is working fine, as you can still view pictures you have taken through the viewfinder. It works ok, but I need this mode switch to fix another camera, so i’ll probably just use what remains as spare parts due to that scratch on the lens.

Let’s get the donor camera disassembled to harvest that mode switch.

There are only about six screws to get the back of the camera taken from the body, you just have to be careful not to damage the ribbon cable that is connected to the mode dial assembly that we are going to use today.

The two cameras, and the mode dial assembly we need to fix the original camera

I did all the disassembly of the original camera to save time, and it took about 5 minutes to get the donor camera stripped down. Once inside there is some insulating material covering the switch assembly, this has to be removed but cannot be reused as it has lost its adhesion. When reassembled I have used electrical Kapton tape to replace the original insulation. This has worked just fine.

New Kapton tape insulation

Assembly involves checking that the button settings relate to the markings on the camera body, this is important at this stage as the last thing you want to do is reassemble the camera to find out that you have the dial in the wrong setup. Do it now and save time and reduce the possibility of damaging the connectors and body clips.

Before and after

Result:

We have a beautifully restored and working and fully functional bridge camera that takes good snapshot photos. It’s not high end, it’s very much a learner camera but good at documenting what’s going on around you. Its mode dial that was missing is now working fine. A little polish and it has come up looking lovely cosmetically. it’s a good little unit.

The camera has come up lovely and is now complete and fully operational

Here are a selection of snapshots from around the home just to prove it’s working as it should. Nothing special, it just does what it was always built to do. Take snap shots.

It works. I’m happy. And another camera has been saved from landfill.

Thank you for passing by, as always it’s most appreciated.

Panasonic Walkman cassette player RQ-P250

At a family gathering this weekend, an elderly family member approached me and asked if I could take a look at his Panasonic personal tape player, and maybe get it back up and working.

Who am I, to turn down such an invitation, so I took it on and promised him I’d have a look into it. There is, “No rush“ I was told. Just as well, as it’s busy in every aspect of my life at the moment.

Here’s the spec:

Type: Auto Reverse Cassette Player

Tape Type: type I, CrO2, Metal

Output: 20mW

Battery: 2 x AA

Power Supply: RP-AC33 (3V DC)

Dimensions: 114.2 x 84.4 x 33.1mm

Weight: 156g

Finish: black

Year: 1993

Hifiengine

Panasonic RQ-P250

Assessment:

It’s well used, and has always been and if I can get it working, will continue to be so. At the grand old age of 79 my brother in law is not about to change his ways and is quite comfortable listening to his old Cassette collection whilst out and about, on trains quite a bit of the time, as he travels up and down the country. He’s a lovely old fashioned set in his ways guy and we wouldn’t have him any other way. It would be blooming lovely to get this back to him working again.

It’s scarred, been well used but looked after, apparently it’s gone from playing quite well, to slowing down and dying completely. I think I know what the issue is but I’m not going to curse myself by saying I know what is wrong, when it actually turns out to be something totally different.

On the Beach – Chris Rea

And I love his choice of music. Let’s get this repair underway so we can listen to Mr. Rea in a lovely crisp sounding manner befitting of an 80s rock star.

Repair:

Batteries in place, earphones connected, push play. No movement from the capstans, and even when put in forward and reverse there is no movement from either capstan. I can hear all the electrical noises such as the tape head picking, and I suspect at the grand old age of 32 years old that the drive belts have probably given in. Let’s open it up and have a look.

And just as I thought. Two drive belts in here, they are both loose, one though is so loose that it has wrapped itself around the two capstans, no wonder it wouldn’t start up.

Two drive belts visible, both so stretched that they have ceased working

I have plenty of these belts spare, I just had to sort out the two closest matching in size. Too slack and you introduce warble, too tight and it will be off speed, you need to get it just right. Adjustments can be made to the motor speed but this will only come back to bite you once the belts wear in.

New belts in place
Old slackened belts

I’ve put two new belts in place, and at some frequencies there is a little wobble, but with Dolby switched in place this can be removed digitally, this will settle over the coming weeks after more use.

I have used some silicon grease on the cogs, I have put contact spray in the motor and the volume controls, and used IPA to clean all the tape contacts and capstan wheels and posts, it’s basically been given a little service to see it forward for a while longer.

Body now reassembled, new batteries put in place, it’s time to test it.

Result:

A quick polish, to tidy up, won’t get rid of the deep scuffs, just makes it a little more presentable. Cassette inserted, headphones plugged in and as expected it’s working just fine, we can hear Mr.Rea in all his gravel voiced glory. So can you, in this video snippet below, that hopefully won’t get a copyright strike 🤞

🎶 On the beach 🎵

So there we have it. Another item brought back to life with about 30 minutes work. It’s going to make someone’s day, and I’m as pleased as punch that I could play a part in contributing to that.

Working well, looking ok after a quick service and some TLC

There you go. Hope you enjoyed this quick fix.

Many thanks for passing by. Always most appreciated.

The Finepix S2 Pro

I’ve purchased three cameras as a job lot in an auction. All of them have issues but the issues have not been clarified. This is very much a “Suck it and see” auction where I get what I’m given. I’ve paid £24:22GBP for all three and that includes free postage. I’ve purchased from this seller before who is a bonafide Camera business based in South Wales. He has no time for faulty items though, quick in and out is his way of working, no time to fix stuff. I’ve got three good cameras in this bundle and this works out at just about £8:00GBP per camera. And where can you get cameras like this for those prices nowadays.

I’ve just read a blog where a guy had one of these cameras from new, and in 2002 he had paid £1550.00GBP for this camera. Wow, and here i am 23 years later paying the grand total of £8:00GBP for one. Even if I don’t get it working, I’m happy with that.

Now this particular camera had two issues in its lifetime that caused concern, and one of them meant it was pretty much game over, and that one was the CCD issue that used to plague this range of cameras. Fuji released a whole bunch of these cameras with a faulty CCD that had to be fixed under a recall. They built sufficient replacement CCDs to cover the recall and that was about it. There were no remaining CCDs left and at that point what was left had become as rare as hens teeth. If you suddenly developed that faulty a later date, then tough…you were stuffed.

Serial numbers affecting CCD problems are listed below:

Model Serial Number Range 

FinePix S2 Pro 31A127**~31A143** 

32A000**~32A039** 

33A000**~33A007** 

34A000**~34A004**

Fujifilm

The second issue was with a batch of these models that had a “bad” resistor in the power circuit that prevented lock up if there was a power spike, if this failed then the camera just stopped and you were stuck. There was another recall on the second issue but there is probably a lot of cameras out there that again weren’t part of this recall. And I guess owners were pretty fed up of recalls at this point and were off loading their equipment as quick as they could.

The serial numbers regarding the lock up problem are listed below:

Between serial numbers 24L00441 and 24L00680
Between serial numbers 24L01057 and 24L01256
Between serial numbers 24L01553 and 24L01863
Between serial numbers 24L10257 and 24L10608

My camera serial number

Above you can see the serial number for my camera. Thankfully my number falls outside the range of any of the cameras inflicted with either problem, so it’s fair to say (Fingers crossed 🤞) that I shouldn’t suffer with any of the known issues with this unit. In layman’s terms I think i may well have dodged a bullet here.

I did speak to the seller regarding the fault on this camera and he stated it was just a general error code on the top screen. There is a general error that arises occasionally regarding certain lenses where they have to be locked on their minimum aperture for the camera to work properly, however I’ve not attached a lens yet so this cannot be confirmed.

Here’s some history:

The Fujifilm FinePix S2 Pro is an interchangeable lens digital single-lens reflex camera introduced in January 2002. It is based on a Nikon F80 (N80 in the U.S.) film camera body that was modified by Fujifilm to include its own proprietary image sensor and electronics. Because of the Nikon body, it has a Nikon AF lens mount and so can use most lenses made for Nikon 35 mm cameras. It is autofocusing, with an electronically controlled focal plane shutter with speeds from 30 sec. to 1/4000 sec., built-in exposure metering and pop-up flash. Its ISO film speed equivalents range from 100 – 1600. The S2 Pro also has sound recording capability. The camera is no longer in production, having been superseded by the Fujifilm FinePix S3 Pro in February 2004.

Aside from the Nikon lens mount, the camera’s principal distinction is its 6.17 megapixel photo sensor. Known as the Super CCD, it is unique in having its photodiodes oriented diagonally rather than horizontally and vertically as in all other DSLR cameras. This allows the use of a sophisticated interpolation system that produces an output image equivalent to 12.1 megapixels. The apparent resolution of images in this interpolated mode lies somewhere between 6.17 megapixels and the 12.1 megapixel interpolated output.

A huge number of these cameras were built using a Sony sourced defective CCD that was subject to a recall by Fuji. The recall ended when the stock of these replacement CCD’s was depleted. There is word that no other stockpiles exist of this Super HAD CCD, making these cameras that are found with the purple or black tinted image problems extinct, only usable for parts. The Fuji F700 used a similar defective HAD CCD, but in 3.1/6.2Mp size. That camera has met a similar fate.

Wikipedia

So let’s hope that we can get some pictures out of this unit. We just have to wait and see what arrives.

Assessment:

Well the camera has now arrived, and I must say it is in an absolutely beautiful condition. Cosmetically there isn’t a scrape or scratch, all screens are scuff free and it looks as if this unit has been well cared for. It just needs a wipe over to clean. The package is just the camera body with no extras such as a body aperture cover or neck strap, but who’s worried about that, they can be procured at a later date.

Nikon type F mount

These units are quite power hungry requiring a total of six batteries. 4 AA cells go in the base and two Lithium CR123A batteries go in the grip. These batteries work in unison, one set handling the basic camera functions whilst the other deals with the capture and processing of images. It’s a strange affair, loosely based around the same setup that was originally on their film based camera counterparts.

AA batteries
CR123A batteries

I’ve had to order the lithium batteries, however I can still get displays and Information using just the AA batteries in the base, basically it is semi functional in this situation.

The lens mount is a standard Nikon F mount, I’m going to have to search through my equipment to see if I have such a lens, I suspect I don’t, so I may well have to purchase a small lens purely for test purposes. I have some other Nikon repairs in the queue, so a lens to have for test purposes wouldn’t really go amiss.

The unit takes either a CF card type II or a Smart-media card (Max size of 2Gb on both) that is located behind a hinged section on the rear of the camera, these work fine and have no bent pins.

Media card ports at the rear

With batteries in place I get the full range of menus, and nothing comes across as suspect at all at this stage in the assessment.

The top menu – no lens attached to test

The top menu by the exposure button is the only “F” indication showing, I have no lens attached so this might be the reasoning for that, but if I do put the menu into manual mode I get the full range of shutter speeds and can even operate the shutter, the shutter seems to be working at all selected speeds with no issues as far as I can see.

Some of the shutter speeds available in manual mode

All other menus are available and I’m even able to format the CF card via the cameras menu. The picture you see on the screen was taken on another camera. It wiped fine so no issues here.

Various menus and the screen after a format was completed through the cameras menu controls

The camera seems to be working with no apparent communication issues as yet. When you try to use the flash it even informs you that you need to insert the correct batteries to test. As I’m awaiting the CR123A batteries I won’t be able to test the flash functionality until they arrive.

No CR123A batteries installed? – You can’t use the flash

As I have stated the testing can only go so far until I have the missing items in my possession, for me that is the two missing batteries and a suitable lens. I’m currently in the process of procuring both. Physically there is nothing wrong with this camera after spending a good couple of hours going over it. I’m quite comfortable with it and believe it could be a lens communication error or just a failure to read the instructions properly by the previous owner. All I need now is that lens. I’ll let you know what occurs in the repair section.

Repair:

To be quite honest it’s not really been a repair, it’s been more of a “pre flight check” to collar a phrase, going through all of the cameras capabilities and ensuring that they are all functioning correctly. As the camera was listed as faulty, and the fault was not identified, I have had to do many hours of testing and Investigation to get to this point.

I’ve done a bit of shopping and managed to buy a nice little lens from the Southern hospice group. Always happy to help a charity and secured this at a good price of £15:50GBP, and that includes the postage, for a Sigma 28-200 f/3.8-5.6 Ø72 Zoom Lens Nikon F Mount. There looks like a bit of fungus on the outermost optic, however I can always clean this if it’s too bad. If not I’ll just leave as is for the moment and keep it vacuum bagged between uses, I can always do a separate post on cleaning up fungus in a lens at a later date. (I have done a basic fungus clean in the past : Canon EF lens 35-80mm)

My new – old test lens

I wasn’t looking at spending too much here, as I only wanted a lens to test a number of Nikon repairs I have upcoming as well as this S2 Pro. This lens will fit that role perfectly, and be added to my collection of other lenses that I have that allows me to test a range of different camera products. I have also purchased an “F” mount body cover for the camera to protect the unit when there isn’t a lens attached to it.

The two CR123A batteries have arrived and have been placed in the handle grip. The warning that was there before the batteries were installed (see picture above) has disappeared and when placed in manual mode the flash fires just perfectly, no issues here.

The Lens has arrived. Good point is that it fits fine and looks good, and all electrical contacts are good. Bad point is it has severe fungus throughout, and is just like looking through a fog.

Severe fungus in the lens

I will do a separate post on cleaning this problem up in a later post. However I’m not overly worried at this point, I paid a very low price so it was to be expected, I’m not complaining to the seller who was a Hospice, they need the money and I can fix it so there really is no problem.

That lovely looking lens hides a problem

The excellent news is that the lens does exactly what it should. The camera indications are good, all working exactly as expected . However the pictures via the screen are extremely hazy due to the fungus infection on the lens. There are no black or purple casts on the pictures so I am quite happy that we haven’t inherited the dreaded CCD issue discussed earlier in this post.

Hazy days – Lens fungus

If I use the lens wide open and pop the camera into auto mode I do get an “ERR33” code and that is a communication issue between the lens and the camera. As I have stated earlier in this post, you have to have the lens set at its lowest aperture and locked for the error code to go. Fortunately this lens allows you to lock the aperture and once this is done the camera takes over the exposure when it is working in automatic mode. So as I also stated earlier, it appears the seller was probably not aware of this requirement/issue.

Result:

We have a fantastic working camera, it does all it was produced to do, it has its little quirks and oddities, but being familiar with these cameras and at least having some knowledge and awareness of how they operate is always a wise thing. Read the instructions and don’t just throw them in the drawer until you eventually sell the camera on as a damaged item, when in fact you were just lacking the knowledge on how it operates in the first place. Instruction manuals are good, they serve a purpose. Knowledge is king.

The complete camera with lens

This camera cost me £8:00GBP. That is a superb price for a camera of this quality even though it is now 23 years old. It has a lot of life left in it, and I can’t wait to get it out and give it a real test.

It’s a little beauty – And the lens that needs attention

So in theory I’m confident and happy that this camera is now in a fully operational order, it’s needed a clean, it’s needed a lot of research to find out how it works, and I’ve also downloaded the operating instructions and repair pack should they be required.

It’s taking pictures and storing them. It’s just the lens at the moment isn’t performing at its best due to its fungus on the optics issue. I’m keeping the pictures stored on the card to compare them with the new pictures that will be taken once I have another lens to use.

Once the lens clean up is complete, if I ever get around to it, I will link it through this post.

Edit:

As 12/7/25 I have purchased a newer higher quality lens without any of the above issues to be able to get some instantaneous results, and as I have about seven other Nikon cameras requiring testing, some with sensor issues, it was wise to invest in a better quality lens. I have purchased a Nikon 28-100mm AF Zoom Nikkor Lens G AF-d, in perfect condition and the post regarding it can be found here: Nikon 28-100mm AF Zoom Nikkor Lens G AF-D

A newer – old lens, much superior quality

As previously stated I will add photos in this post once the new lens arrives, to show the difference from the fungus infected lens to a decent lens. The old lens is still a work in progress and I will post about it again as a separate post once the clean up is complete. It will probably be a job completed once the long winter nights are back in situ.

Below are comparison photos between the old lens with fungal issues and this new lens:

It’s just typical for me to manage to make another post from an issue that has arisen from fixing a different item. But isn’t that life? Continuous improvement is a factor we come across on an almost daily basis, and if you deal with old items as much as I do, then there is always something else that needs repairing, something that requires your attention and I just love that. The ability to improve or make something better, gives such a feeling of achievement and accomplishment, and total satisfaction. And that’s why I write this drivel. It’s for me, it’s what this blog was originally set up for. It’s my journal of what I do.

Many thanks for following this post. You know it is always very much appreciated.

Sinclair Cambridge Memory Calculator

What the listing stated:

This auction is for a used cased Sinclair Cambridge Memory pocket calculator and original case. The item is in very good cosmetic condition as is the case which still has its instruction sheet. The item is powered with 4 x AAA batteries (not supplied) and does work although 1 of the digits is faulty and does not display (see pictures) plus the number 5 digit is not working. Please refer to the pictures and description provided before bidding.

EBay

It’s faulty…obviously

So it does work, but it doesn’t? This calculator is a model one memory calculator, that dates from around July 1973, ( Actually May 1975 see photos below) and is one of the earliest available mass produced electronic calculators available in the UK at the time. And it was produced in collaboration with a guy called (Sir) Clive Sinclair, who in the following decade would become synonymous with tech development in the UK. It retailed at £29:95GBP, and given the rate of inflation, its cost today in 2025 would be a staggering £463GBP. Wow!

Courtesy of Vintagecalculators.com

I love collecting old calculators, I couldn’t afford one back in the day when they arrived on the scene as I was only a child and probably only on about 20 pence a week pocket money, and savings and investments were not even known to me at this period of my life. The thought of saving that precious 20p a week for the next 150 weeks wouldn’t have even remotely crossed my mind. What no sweeties?

But I can buy them now, so no big issue!

So this one has become available, and I’ve been tracking it for a week or so, there were nine other people watching but I secured it for a total including postage of £14:49GBP, and I’m happy with that, it’s a piece of retro history for a very good price. Even if it remains faulty, or should I say working but not working?

This unit obviously has its problems, the button number 5 doesn’t work and one of the led digits is also not functioning. Hopefully I can get these issues sorted and soon have the calculator back up and working as it should. That would be nice. I’m looking forward to this little project.

Assessment:

It’s arrived and it’s a lot smaller than I anticipated. It has a separate hard protective case, which is a nice touch and a small info sheet on its operation. Cosmetically it’s in a good condition with just minor signs that are age related. There are no gouges or scars so it has been treated well, though it’s not pristine.

Two buttons unresponsive and one LED

Batteries go in ok but, I believe old style AAA batteries were a little wider than those used today and would sit a bit more snuggly in the battery compartment. As you can see there is a little wriggle room here, and springs at both ends need adjusting to help prevent this. I may have to use some spacers so the batteries sit tighter in place.

Gaps between batteries – means movement

The switch is a bit temperamental and can be seen quite plainly from the battery compartment. It looks strangely out of place with no batteries in place.

Switch off
Switch on

It is such a basic design solely relying on tension of a small metal plate to short across the connection points. Should be a simple enough issue to sort.

There is a little battery contamination on one of the battery contacts, again this shouldn’t be too much of an issue and should clean up ok with some IPA.

Some battery contamination

It was originally reported that there was one unresponsive button this being the number “5”, there is also another unresponsive button, the multiplication “X” button. There is also one LED indicator, the 4th one in from the left hand side that is not operating. Add to this the issue with the On/Off switch and the contamination, and the original faults reported in the original sales pitch have now doubled. I just wish people would spend more time going over the issues and then give actual accurate feedback as to what the real faults are, it would make for a far more pleasant buying experience. Rant over.

There doesn’t seem to be a single screw holding the body together, I just hope it isn’t all heat welded.

Let’s try to get inside.

Repair:

Well it cracked open quite nicely with no issues with just a plastic flat prise tool. The main board just sat comfortably in the unit, secure, and not a screw in sight. Strange as time moves on some of the games units I come across have best part of fifty of the little blighters to remove before you get anywhere. sometimes the old way is good.

Bare board
Opposite side of board
Date is May 1975

The dismantling of the keyboard is a little complex and you have to take time and make sure you know how it’s going to go back together, it’s just a bit fiddly. The board is quite straightforward and as soon as I see some of the IC’s it dates the unit perfectly. The chips are dated May 1975, and that is about 18 months younger than what I originally thought, it’s quite informative to get inside and learn occasionally and this is just as good as having a birth certificate presented to you. All good stuff.

I’ve proved that there isn’t a problem with the missing digit on the display as using my multimeter in diode mode I am able to prove that this LED is working fine.

LED working

The picture shows just one part of the display range on this particular digit, I can assure you all other sections of the display are also working.

Regarding the case with the buttons not working. I have checked this out for continuity and both digits go through the same portion of the main IC and there doesn’t appear to be any broken traces. It’s a strange one but I have also found some really poor solder joints that are either cold joints or just poorly soldered from the start, there are a couple of resistors that need re soldering. It may be nothing at all, but it needs attention, a full reflow wouldn’t go amiss or take too much time.

Faulty resistor joint

I’ve reflowed the entire board due to there being a few cold solder joints.

Full reflow completed

On top of this I have taken off two old capacitors and tested them out of circuit, and both were out of their operable range of +/- 10%. As a result of this I have replaced the offending components with comparable new ones.

Old capacitors
New capacitors

Even with all these extra tasks being undertaken there is absolutely no change in the way it operates. Nothing has gotten worse, the faults that were originally there still remain. I have done some research on line and carried out some further tests and checked expected voltages, most are within range except one that appears to be less than its expected value. After testing everything on this board, every component I can only surmise that one of the three chips has failed, I suspect very much that this, the main chip, a CZL550 integrated circuit. Otherwise known as “Calculator on a chip” is the one that is at fault.

A CZL550 chip

To be quite honest these chips are fairly rare and command a price far in excess of what I paid for the original unit, and I don’t really want to do that. I think I’ll wait around to see if I can secure another faulty unit to complete this repair, so in the meantime, and until I can secure such a unit I will put this repair on hold.

Result:

Well, it’s not what I wanted but sometimes you just can’t win with some of these old projects. In no way am I walking away from it, it’s just that the parts are so difficult to get hold of that you really do have to just wait until a sufficiently faulty one comes up for sale. And that could be days, it could be weeks or months. So for now i admit defeat, but it will not be going to trash. It will remain in my ever expanding “To do” box, for me to pick up on at a later date. And when I am in a position to move this project on, I’ll pick it up in a continuation of this post.

Many thanks for passing by. It’s always appreciated.

Polaroid Snap camera

What the listing stated:

Untested

EBay

Hmm….EBay untested, the number one way to try and flog knackered crap without accepting any responsibility. Caveat emptor as they say “Buyer beware”. Hey, I’m a rebel it might even work…who knows?

The camera I have purchased

About this camera:

The new Polaroid Snap camera attempts to recapture the fun of instant photography, but with a modern, digital twist. 

The Polaroid Snap prints out 2×3 inch photos straightaway using ZINK (Zero Ink) technology, and can even store a back up of the photo you’ve just printed on a memory card. The ZINK paper also has an adhesive backing so you can also use each print as a sticker if you wish. 

You don’t however get a rear screen, or an electronic viewfinder. There’s also relatively few changes you can make to settings. The Polaroid Snap is available in four different colours, with one of its unique selling points being a relatively low price (£89 in the UK). 

This cost doesn’t take into account the price of supplying it with the paper which you need to print your, er, prints though. 

The Polaroid Snap has a 10 million pixel sensor, and a fixed length lens. It was designed by the Ammunition firm, which has made its name working with the likes of Beats by Dre, Square, Lyft and other big brands.

Amy Davies – photography blog

The fact this camera has gone at such a low price speaks volumes to me. I suspect it has numerous issues. I have recently been working on a number of these “Instant” cameras namely the Fujifilm Instax range that are quite good to be honest on a similar photo output size of 3×2 inches. I’ve decided to have a look at the original Polaroid-range and this Snap camera became available. I believe these cameras came out circa 2016. The difference between this and original Polaroid cameras is that this one uses a 10mp camera and uses an additional SD card. With this camera you can also frame your shot using a number of different add ins and print using Polaroids Zink paper. The paper is a thermal type, and the picture quality is not all that brilliant if what I have read is to be believed. This camera is a bit more “advanced” than the basic Polaroid of the 70s, hence there is a bit more that can go wrong with it.

It originally retailed at £89GBP and is now discontinued. Current prices are between £20-£40GBP and I’ve purchased this one with postage for a total outlay of £10:94GBP. Film prices are similar to that of the Instax range.

Now we can do an assessment of what has arrived.

Assessment:

This camera is dated inside as November 2016, so it is currently a youngster at only 8.5 years of age.

It’s arrived and it’s a nice little unit. A little unclean but this will buff up ok. The battery is dead, but once I plug in a micro USB it’s charging ok.

Charging indicator

The port looks fine so there is no issue here. I open the back and whoops! There is some film inside but I hope this doesn’t fog! This is a film that uses a thermal printing process, but does still have its sensitivities. And in the SD card slot is an 8GB card, so for the price I’ve paid for this unit the card is a superb bonus.

All lights up
Smart look
8Gb Sd card – Bonus
8.5 yrs old

And as I’m impatient, I switch the camera on after a short charge and I take a photo, after adjusting a few settings the printer kicks into life and a picture starts to appear.

We have a picture

There were only two film pieces inside and I suspect they have been in there a few years as they are yellowed through age and this is noticeable on the rear where they are very yellow. I’ll have to get some new film to test for real.

So, at the moment it’s all looking very promising, the picture isn’t brilliant quality but that has always been an issue with these units, however I believe a copy is saved to the SD card so you’d always have a reference. The printer is a bonus I guess, for printing out those special moments that you want to see instantly just like good old Polaroids. As for repairs I suggest at this point there is very little wrong with this unit. I do though have to explore its functionality and settings and do some reading up on the basics. When I’ve done that I’ll have a better idea.

I’ve checked the SD card and can confirm it is taking pictures without the need for paper and saving to the SD card as it should. It did also contain 110 pictures of what looked like holiday photos from the original owner. I have contacted the previous owner and they have stated the photos aren’t required so i have reformatted the card. There lies the security issues with selling such items and not checking prior to sending off to strangers, it really is basic security folks, delete and format before selling anything to anyone.

The only items that seem to be missing from this unit are the charging/transfer cable of which I have quite a few, and a magnetic lens cover that really isn’t necessary. Other than that it’s a complete unit.

Repair:

The battery has been left to charge, and this has been achieved with no issues at all. All indications are as expected.

All charged – no issues there

The unit has been cleaned and this has come up lovely, I know the actual camera works as viewing the results on the SD card confirms this, and for a 10mp camera the results aren’t all that bad.

I now just need to get some film to check out all the features that are available, only then can I really say the camera is working.

There are only really six options available here on the camera, via the dial on the top you have the choice of black and white, sepia effect or full colour, and on the next button you have a choice of with or without the Polaroid type frame, hence that is your six possible options. I’ll show some examples of each below.

Colour – frameless and Polaroid frame
Black & White – frameless and Polaroid frame
Sepia – frameless and Polaroid frame

Result:

What a cracking little unit.

And it’s working
Looking pristine and clean

As basic as basic can be but a great fun item all the same. Nothing technically wrong with it and sold as untested just because the owner couldn’t be bothered to charge it and check it over. Their loss is my gain to be honest, and I inherited an 8GB Sd card as well, one of those rare occasions that you buy such an item and it falls in your favour. I deserve one of those moments to be honest, most of my purchases are faulty junk. This makes a pleasant change.

Im keeping this, for the while. There may be another youngster in the family interested in this one. I’m looking at obtaining the next one up in this range to see the differences, and the advancements that they have incorporated. (It must be broken of course 🙂)

Thanks for passing by, as always much appreciated.

Sangamo Weston Master V light meter

What the listing stated:

Sangamo Weston Master V  Exposure Light Meter includes Invercone & Cases The exposure meter is not working The invercone will also fit the Weston IV

EBay

Weston V light meter and Invercone

I have brought a little item from my past history here, going way back to the days when you had to work out the light levels in photography for yourself. The exact date of this unit is unknown, however it was manufactured between 1963 and 1972. That’s two years prior to my birth and up to the age of when i was 7 years old. And I was using them when I went into photographic work approximately ten years later. These units were made to last and did their job well, hence their longevity. I’ve paid the total cost of £8:40GBP and that includes postage. I’m surprised to be honest as not only is it the light meter, but also an Invercone (I’ll explain later) and two cases. An absolute bargain in my eyes as the Invercone itself, in a case can sell for more than I’ve paid for the entire package today. Oh, and it doesn’t work and to be totally honest I don’t think I will be able to get it working ever again, as the suspected component fault is one of those little things that are only dealt with by specialist craftsmen. Add to that the problem of locating a replacement piece, as they are nigh on impossible to obtain, or in layman’s terms, as rare as hens teeth.

But I have read about people reviving these parts and I’m going to give that a try. If I’m unsuccessful it will be a nice piece to get mounted into one of those box frames as a historic photographic memento.

What is this part you’re referring to?

A light meters main purpose is to react to available light and direct the photographer toward making a decision regarding the settings for his camera. Things like ASA, shutter speed and f stop settings.

Therefore it needs something to sense the light. It’s not a solar panel, these were not invented back then, but it was a similar system and it was called a selenium light sensitive cell. When exposed to light, the cell generates a small electric current that deflects the needle of an ammeter coil within a strong magnetic field. The whole system is basically a Selenium cell, a resistor and the ammeter coil. The lightmeter is entirely dependent on the light sensitivity of the selenium cell for accuracy. Over many years the selenium cell ages and degrades to the point that it just stops working. It dies. Its main cause for demise is usually moisture getting into the workings and causing degradation at the contact points on the Selenium cell.

There are a number of posts/sites I have visited that claim you can revitalise these items, however I am sceptical at this. There seems to be only one person in the uk that seems to totally replace these items and that is a guy called Ian Partridge, who I believe charges around £90GBP for a repair and his site can be found Here. A fully working serviced unit can sell for up to £189:00GBP.

I’m not doing that. No way. I’m going to see if I can even get it slightly working, I’m never going to use it seriously again but I’d at least like to see the needle moving without causing any damage to its original design.

Is that the only potential issue?

No of course not. There is one other potential reason why it is not working and that is related to the ammeter coil, the axis on which the needle moves, sometimes it can become stuck, if this is the issue then happy days, the fix would be a lot easier. However this is me, and things are never that easy for me 😂

There is also a fine tuning screw on the rear that someone may have been a little bit too enthusiastic with, in the past.

And of course. The pointer lock on the side of the unit could have been simply left on. Now wouldn’t that be nice and easy?

So what’s this Invercone thing you’re going on about at the beginning?

It’s that weird shaped piece of plastic with a bit of metal on it, in the pictures above.. it assists greatly in incidental lighting conditions where there is a back lit scenario.

The inverted cone shape is designed so that as the meter is angled to the light source, the readings remain accurate which they would not do if it were a dome. And because backlight effects the exposure, a small part of the invercone sticks-out beyond the top of the meter case to pick any such light up.

westonmeter.org.uk

A little history lesson…

Sangamo Weston was a company that made light meters, among much other electrical equipment. It is particularly known for the Weston Master series of selenium meters.

The Weston Master V was produced in the UK from 1963 to 1972. It was Model S461 in the UK and Model 748 in the US

Weston was founded by chemist Edward Weston—no relation to the famous photographer—who held many patents for electrical inventions, from permanent magnets through cellulose manufacturing, dynamos, arc and filament lights and the magnetic-drag speedometer to electrical measurement instruments (and even US 895218 – a fruit box!). Weston’s son, Edward Faraday Weston, applied for a U.S. patent on the first Weston exposure meter, granted as No.2016469 in October 1935. This was a cylindrical case with an electrical meter at one end, and an iris at the other; an adjustable scale around the meter opened and closed the iris, and showed the exposure. 

Sangamo was originally “Sangamo Electric Co.”, in Springfield, Illinois. It set up a British subsidiary in 1921. Sangamo acquired the Weston Electrical Instrument Co. in 1936.

Since Weston was one of the first makers of light meters, before film speeds were standardised, Weston had its own film speed scales.

At some point, Weston products were distributed by Ilford in the UK. The company was bought out by Schlumberger in 1976, but still exists, making electrical timers.

The EuroMaster light meter, very close to a Weston design, was later made by a company called Megatron.

Assessment:

For those who have made it this far, well done and thank you. Let’s have a look at what has arrived and assess the overall condition. It’s taken some time to arrive what with there being two recent bank holidays closely placed in proximity to each other in the calendar. Translated that means the UK comes to a halt during this period, whilst everyone gorges on poorly cooked barbecued food in bad weather whilst drinking too much alcohol.

And some of us are just working. Most annoying.

Anyway enough of the whining, here’s the assessment:

The meter has arrived and is in an excellent cosmetic condition, it came in a small leather case with a lengthy string neck strap. It’s all original and is still marked up with the original owners details on a small label. The Invercone is just what it is, a piece of shaped nylon/plastic and not much to rave on about. It is as it is, in good condition and also in a small leather case.

Original case
Excellent cosmetic condition

The calculator panel on the front is undamaged and in full working order, the light baffle on the rear is also operating as it should and the info panel under the viewing glass changes as the baffle is operated. The pointer lock is operating as is the fine tuning screw on the rear.

Baffle closed
Baffle open

There is a very slight movement when exposed to intense sunlight with the baffle open or closed however it is only very slight. It struggles to move past the zero indicator on the scale, hence as described it is safe to say that it is not operating as it should. We will have to look inside to see if there are any obvious issues, however I strongly suspect it is related to the Selenium cell. I would like to see if we can get this operating, I’m not overly worried about its accuracy as I’d just like to see it move through its entire range. It would be good to see if it is at all possible to revive a “dead” light meter. We can only learn from dismantling and investigating such items.

Repair:

I’ve left the unit in sunlight for a few days, as this has been known in some rare cases to just kick start it back into life. That doesn’t seem to have worked in this case so let’s have a look inside.

Remove securing thumb screw
Remove two nuts
Case lid lifts off
Carefully remove fascia plates
Remove sliding needle lift mechanism and expose selenium cell
Cell, armature ring and ammeter coil removed
Cell connecting ring cleaned
Cell contact ring, cleaned and renewed

The whole unit came apart quite easily to expose the selenium cell deep in its workings. Using a multimeter on the cell, indicated life in the item as values changed as the cell was moved from the dark into the light and vice versa so I am confident there is some life still present in this cell, but is it sufficient to power the meter? I have then used the lowest Ohms setting available and put the negative lead on the magnetic case (Ground) of the ammeter coil and the positive lead on the wire connected to it and there is no movement at all. This indicates to me that the ammeter coil is at fault and unresponsive to any voltage, I believe this is the problem and at this point the repair is not possible. I have cleaned the cell connecting ring to the point that it is now shining and free of any age related contamination. The contact ring on the cell itself I have revitalised with a metallic silver pen. I have checked continuity and that is also good and acceptable. One thing I did not see in this model was the use of a resistor that is used in most selenium cell light meters between the cell and the ammeter coil, maybe there was never one used within this range of meters, I’ll have to check that out. I have checked this out via numerous sources and it appears the Weston light meters never had a resistor placed in line at any point, so that has cleared that question up. This unit is dead due to a faulty ammeter coil.

Result:

The unit is cosmetically very good and I believe the actual selenium cell is functioning but at an exceptionally low level. The tests on the meter ammeter coil have come back negative indicating that there is no life in this part of the meter. I suspect the fine wires on the coil are possibly damaged. The only way I can get a working unit would probably be to obtain another faulty unit to transplant parts, I may well do that in a later post.

I hate not getting the fix done, however this unit is in excess of 50 years old and to be honest the odds were stacked against me from the start. I did state that I may actually mount this item in a frame as a photographic art piece, that may still happen but I’d love to prove the original cell is still functional if I can. Maybe I just might buy a donor unit to test my theory on.

I’ve learned a lot from this post on the repair and dismantling of these units so that is a big positive. Knowledge is always king as they say.

It will not go to landfill. It will be reused in some form, you may even yet see a follow up post regarding it.

Thanks for passing by, it is always very much appreciated.

EBay

The seller here has obviously used the wonderful AI assistant to write this post as it is so false. The unit is incomplete, it is probably not sought after, as it was not that well received back in the day, and in its current state is probably only fit to be disposed of, also an important part of it is missing. However I’m not for disposing of items such as this and will endeavour to get it back into a working state, it’s just going to take a little time and patience.

I’m missing a fair bit, and it doesn’t work
What my unit looks like
What the unit should look like

Some history:

Peter Pan Playthings Ltd was a British toy company founded in 1963. It bought Salter Science and other assets from the receivers of Thomas Salter Ltd. In 1972 the company reported a £80,000 profit. The following year it was acquired by Berwick Timpo.

The company was sold on to Bluebird Toys in 1987, which continued to use the Peter Pan Playthings brand for several years.

Produced around 1980, the Master Challenge system was licensed from Coleco (Coleco’s Quiz Wiz system), this was released in the U.K. by Peter Pan Playthings. There were 30 different cartridges for Coleco’s version. The unit comes with a question book and the system is used to answer those questions. It is currently unknown how many cartridges were made for the UK version.

T’internet

So for some unknown reason I have purchased this 45yr old piece of retro nonsense because I just can’t keep my bidding finger still. That’ll teach me a lesson. I’ve paid the grand total including postage of £5:69GBP, and I think it is missing the most important part, the book of questions that go with the cartridge, usually attached to the binder that encompasses the unit. It’s also broken, so it needs fixing anyway, and I believe extra cartridges can be purchased, so if I can get it working, and I can obtain further cartridges then no problem. If I can’t, then there is a problem. The battery cover is also missing. I’m a fool, honestly I am.

Whereas the Coleco Wiz system had 30 different cartridges available I believe the Uk version only had the 6 as listed below:

  • 1 – General knowledge
  • 2 – World of sport
  • 3 – Music
  • 4 – The bible
  • 5 – BBC quizzes
  • 6 – BBCs Top of the form

And back in the 1980 these additional cartridges and quiz books could be purchased for £6:99 GBP and 50 pence postage! Quite pricey for the time.

On this particular cartridge or what remains of it are the pre programmed answers to 1001 questions that I’m not in possession of. How novel. I have managed to find a photo on line that has some questions showing on it, these would have been in the original book that would normally be attached to the binder of this unit, so this should be sufficient to at least test the game in its current form.

Some questions to test the unit.

The game works in such a way that you choose a question from the book, you then use the unit to give your answers. If the answer is wrong you hear a corresponding low pitched sound and get a red light. If you are right you hear a high pitch sound and see a green light.

Score sheets in the back of the booklet

So basic in its operation, many thought it was totally pointless back in the day. However this was computerised technology in its earliest and most basic form and was at the dawn of a new era of personal entertainment. It deserves to be preserved.

To cover my apparent foolishness I have found another cartridge that I’m going to purchase to make this unit complete.

These plug in units come in a binder format with the brains of the game situated in an enclosed plastic block on the base of the binder, i suspect it is something along the lines of an integrated circuit. I can’t open this one as it is sealed, however when the old one arrives i will open it up as that one doesn’t have a quiz book with it. It will be good to see just what is inside. This little unit contains all the answers to the 1001 questions that are provided in the attached quiz book that slots into the top of the binder. The number inside the block indicates the quiz book reference.

The “Brains” and the quiz book reference number

The faulty computer unit I am awaiting, then slots into the binder and block by the pins you see in the photo above. The computer then simply has to decide whether your answer choices are right or wrong. And that’s the crux of the game in a nutshell.

Whilst awaiting this broken units arrival, I’ve purchased the additional set of plug in questions seen in the pictures above. This is an additional 1001 questions set, based on all the old BBC quizzes. It’s complete with answer book and the complete surrounding binder. It has arrived ahead of the faulty unit and is in an exceptionally good condition considering its age. None of the mustiness you’d expect from an item that is 45 years old. It must have been stored with great consideration. It’s cost me more than the broken unit, this cost a total of £8:15GBP, so that makes a running total of £13:84. I do have another game cartridge on order that I picked up for another £7:83GBP but I’m quite happy with this. It will be a nice addition to the games box that comes out when the family or guests come around, and everyone loves an old retro style game. It will certainly be a talking point, that’s for sure.

My additional plug in cartridge

Assessment:

I’ve not even received the unit yet and I’m getting a bit ahead of myself wondering just what could be wrong with it. Its operation is so basic, think it could only be one of five things possibly be at fault.

  • Pins that read the cartridge are dirty/damaged
  • Contamination in the battery area
  • Loose wires
  • Faulty switch
  • Cold solder joints

I guess we will just have to await its arrival when we can make an accurate assessment.

The unit has arrived and it’s a tatty looking piece. Dirty, and only the remains of the binder that used to accompany it.

What has arrived

I’ve put in some batteries and there is very dead. There is the occasional buzz when the switch is slowly moved but nothing else. It could be a faulty switch, it could be the contacts. I’m going to have to open it up and get down to board level.

Inside – all posts welded

The problem here is that inside there are no screws attached to the inside support posts. The whole unit has been welded, all plastic posts have had heat applied to moulding the post tops. I’m going to have to break these off and try to re-weld them when we’ve got it all working again….if we can.

In the meantime I’m going to open up the the plug in module that’s attached to what is left of the old binder, i might as well sacrifice that piece as it’s of no use to me and it’s in the name of research.

How the unopened board looks
Board removed front view
Board removed rear view

Now I thought they’d be some kind of integrated circuit in here but there is not. It appears to be just a board with two sets of comb like traces that would appear to just short together in the unit. Makes you wonder if the questions in the book follow some simple kind of algorithm that the unit just adheres to. Maybe every so many questions, they all have the same answer, there must be some simple and basic way that the unit knows the preprogrammed answers. Maybe I’ll find out more when I look inside the actual “Computer” unit.

Repair:

Inside the unit there is not a great deal of components apart from a single IC a capacitor and a number of diodes and resistors.

I’ve used a very fine emery board I borrowed off of my wife (don’t tell her) to try to get in and clean these contacts, as I believe this is what is causing the issue.

All buttons under a sheet of tape

All buttons are under a sheet of tape. I have removed this tape, cleaned all the contacts with IPA and repositioned them and re taped them using Kapton tape. They are a lot cleaner and are clicking nicely.

The contacts where the game cartridge is inserted are quite contaminated so these also have to be cleaned.

Contacts are contaminated

I’ve used an emery board to clean the contacts up on the unit, and when the cartridge is inserted we have a result. The first ten questions I have input have had correct answers only and no duplicates, so it really does really look as if the contacts were contaminated causing some kind of issue with the two parts of the game communicating.

Result:

It’s had a good clean both inside and out and a few of the old items inside replaced and given a new lease of life. The unit is now fully working and can be seen doing so in the little video below.

A little test example

I’ve since purchased a new binder for question set 1, so I now have that along with question set number 5. I’ll keep an eye on the auction sites to see if any of the other sets become available, and who knows I may try to get a full set. Now that would be quite rare I’d imagine.

A nice clean and working unit

I love digging around in these 80s units and just wonder at how basic the technology was back then, it’s just amazingly simple and so well put together. Anyway, this one is now working and good to go for a few more years yet. Saved from landfill we have another successful repair under the belt.

Thanks as usual for popping by. It’s most appreciated.

Fuji Finepix S1500

I purchased this item from EBay in April 2024 and have only just got around to finishing what had been a draft post put together all that time ago. I had written about it briefly in this earlier post Fuji Finepix S1500

A little bit about this digital “Bridge” camera

Successor to the S1000FD (at the time the world’s smallest 12x zoom camera), the FinePix S1500 is the latest in a long line of very compact SLR-styled big zoom cameras designed to appeal to those wanting a lot of lens on a tight budget. The big change is the inclusion of optical (CCD shift) image stabilization, making the long zoom a lot more usable in less than perfect light, and for the money you’re getting a lot of features – including full photographic controls and a 7.5fps burst mode (at reduced resolution) – in a lightweight package. Price on the market back in 2009 was £219:00GBP

DP Review

Assessment:

This camera was launched in 2009. The unit has arrived and is cosmetically tidy, however when you open the battery door the issue is obvious, two of the contacts are badly corroded and despite some initial cleaning there is no continuity and no power present. The unit is very much dead and not working.

A tatty and unloved camera

The issue with these units is that the power chambers are hard to access and to get to the point where the battery connectors are, you have to remove the powerboard assembly and this involves de soldering a number of points. There does not however appear to be any major signs of corrosion on the visible side of the board, when it’s removed it may reveal a darker issue hidden below.

Power board assembly

It’s going to be no easy task but I may look at running six volts from the bench power supply to a point on the power board assembly to see if I can breathe life into this camera. I don’t want to waste time in the battery terminal area if there are issues elsewhere on the unit.

The corrosion on this camera is horrendous

Repair:

Looking at the boards again I am not going to pay them any further attention. The contamination has not reached under them and is isolated to the battery chamber so that’s where I will concentrate on.

I’ve started with the contacts on the battery door, as you can see above, they are particularly bad and have no continuity through them.

Corroded door
Contaminated contacts
Badly corroded
All clean

When reassembled the door section looks good, it will just need a good clean at the end.

Before and after

Rather than dismantle the whole camera, and because I know there is no contamination on the main board I was able to get down into the battery chambers with a steel braid pen that I have, that allows me to gradually scrape off the contamination. Followed off with a good chamber clean of Isopropyl alcohol, I was able to get the remaining acid contamination out of the camera.

Attacking the contamination in the battery chamber

Result:

Once I did all of this I paid some more attention to the exterior using some car cockpit polish, this removed those horrid white sweat marks you see on the faux leather coverings of these older cameras, and it came up quite well and had a lovely vanilla smell to it .

Looking mighty good….and clean
Polished

I have turned it on and hey presto we have life. Everything is working as it should. It’s a 10 Megapixel camera and I have a 1Gb Sd card installed and it is taking pictures as expected.

And it works

Nothing more really to say about it, it cost me about £6:00GBP spares and repairs as it was totally dead, thankfully we’ve managed to get it working instead of breaking it up for spares that would more than likely never be used anyway.

Finished item

This unit is of no real use to me, so I will get it up to our local Hospice shop for them to sell on.

LOROS our local Hospice

Even if they only get a few pounds for it, it will benefit someone who needs the help and assistance.

So another item saved from the scrap heap. Might be of use to someone.

Thanks for passing by.
