Sharp OZ-7000 Wizard

The Sharp OZ-7000, Amongst one of the first electronic organisers and precursor the PDA. Needs repair. Or does it?

What the listing stated:

Not working. I have replaced the two batteries and cannot get it to work. I have not touched the memory battery. See picture for actual item. Case is a bit sticky unfortunately with age.

EBay

First of all, what is it?

The Sharp OZ-7000 Electronic organiser / Calculator

The Sharp Wizard series, introduced by the Sharp Corporation in 1989, was among the first electronic organizers and a precursor to personal digital assistants (PDAs). The debut model, the OZ-7000 (known as the IQ-7000 in Europe), combined organizer functions with an IC Card expansion system, allowing users to install software and memory cards. Over time, Sharp refined the series with larger displays, increased memory, and enhanced features, such as infrared communications port for wireless data transfer, touch-sensitive displays, and clamshell designs.

The out-of-the-box functionality of the OZ-7000/IQ-7000 included a memo pad, a telephone pad, calendar and scheduling with alarms and repeating events, multi-time zone clocks, and a calculator, thus covering all the basic functions found in PDAs since. The keyboard was not QWERTY, although later models, starting with OZ/IQ-8000, changed the orientation of the screen and keyboard layout.

The OZ-7000 was about 6.3 inches (163 mm) tall, 3.7 inches (94 mm) wide closed, 7.25 inches (184 mm) open, and 0.85 inches (21.5 mm) thick closed, making it much larger than later PDAs. It featured a serial port (proprietary connector) to attach to a Windows PC or Macintosh or another OZ-7xxx/OZ-8xxx device, an optional thermal printer port and a cassette tape backup. The OZ-7000/IQ-7000 model featured 32 kilobytes of internal memory and a 96 x 64 dot (8 lines x 16 characters or 4 lines x 12 characters) black and white LCD with controllable contrast but without a back light. A major advertised feature of the model was the IC Cards expansion slot for accessory cards developed by Sharp.

A bit of a break from the mountain of photographic equipment I have been dealing with lately, I thought I’d take a bit of a detour and have a look at some prehistoric PDA gear, as I have also done in the past, as you will no doubt be aware of, if you have ever read any of my posts on Psion organisers.

From what I can gather, this one is a little beaten up and battle scarred, and quite simply does not work. I’ve paid the princely sum of £8:54GBP after i managed to knock the seller down by a few pounds. I just now have to await its arrival before we can carry out a thorough assessment.

Assessment:

Its here, everything is as it should be apart from the base being a bit loose in one corner where the clip inside has broken, however that’s not an issue and can probably be repaired.

The broken clip

The exterior is a little sticky but again, this is just one of those 1989 rubber enhanced products where the vulcanised rubber coating has started to degrade. A post I previously published shows how I deal with these 80’s degrading rubber issues: Sticky, Rubber camera grips

Front case
Rear case
Both sides of the case are sticky and require cleaning

The unit has three batteries, under the rear shell. These are two CR2032 and one C1616 coin cell, with the C1616 being the units memory battery. These batteries will need to be tested as this unit does not start up, the whole unit is dead. The previous owner has stated that they have changed the two main batteries but not the memory battery, testing them will tell.

The three batteries

Beyond that, all catches, buttons and switches seem to be performing as expected, no cracks or major damage to the external shell, or screen area. Naturally there are signs of usage as you would expect on an item that is now 36 years old, light signs of age related wear and tear, nothing of concern that is detrimental to its operation.

Repair:

I’m leaving the broken clip on the rear shell as it is, it’s not visibly exposing anything of the interior and to be honest needs quite a bit of force to show the gap, it’s not a problem and not necessarily requiring a repair. In normal handling it is not even noticeable, so it will remain as it is.

The main fault, and I apologise in advance, as it was not really a fault, was a misunderstanding of the unit’s operation by the previous owner. When you take the back off and change the batteries, you have to operate a switch so as to not interrupt the backup of the system.

Battery backup switch there is a “B” and a “A” setting

There are two modes and these are explained below. This switch is located inside the battery compartment and is used when replacing the main batteries to prevent data loss.

  • B stands for Backup, a setting used during the battery replacement process. The device relies on a small, separate backup battery (often a C1616 coin cell) to maintain memory while the main batteries are removed, provided the switch is in this position.
  • A stands for Active (or simply the normal operational position), which is the standard setting for everyday use once new batteries have been installed. 

To replace the main batteries safely and avoid losing your data, you must follow a specific procedure that involves setting this switch to “B”, changing the main batteries, and then switching it back to “A” after the new batteries are inserted. 

The issue here was that the batteries had been changed and the switch was put into the correct “Backup” mode. However the previous owner had not placed the switch back into the ”Active” mode when the batteries were changed and the back of the shell was put back in place. Hence the unit would not work as in theory the batteries were locked out of use. On opening the shell up, this was the first thing I looked at, and when the switch was put into the correct position the unit sprung into life once the “On” button was pushed.

When the switch was set, power applied and the unit reset to 1989

When the unit was turned on it then reset to 1989, I was able to change the times and date, and I was pleasantly surprised to find out that the date range on this unit covered the years 1901-2099. Considering this unit was released 11 years prior to the Y2K bug of 2000, it showed some advanced thinking in the implementation of these units.

Happily updated to the current date and year

One of the issues with this particular unit is that there is no backlight on the display, the display is black and white and the only change that can be made is to the contrast. Back lights eventually arrived with later models. So use of these units was pretty much limited to daylight hours, or whilst under a light source of some kind, that said the display is very good and has a good contrast range.

In use in the carpark at work

The last thing I have done is clean with some IPA to remove the years of gunk and I think this was quite successful

The IPA certainly lifted some dirt

After this I have finished off with a nice polish with some car cockpit cleaner. It’s finished this repair off just nicely.

Result:

Here we have a nicely presented, clean and fully working example of a nice little bit of personal computing history.

So. With these older items, it’s sometimes good to just have an awareness of how these old timers operate. Get an instruction manual, study how it works, it can make the difference between selling it as damaged, when in fact there really was nothing really wrong with it. The seller could have sold this for 3 or 4 times the value that I purchased it for, but I’m not worried about that, as far as I’m concerned I got myself a bargain and to be honest, that doesn’t happen that often.

It’s a win win situation as far as I’m concerned, I win as I now have a lovely example of pre PDA technology, and it’s a small win for the environment as another piece of “Waste” has been saved from landfill.

Thanks for passing. Thanks for being there. Always 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.

MB – Simon

Remember this? Everyone had one around 1978 apart from me that is. Well, now I’ve got one, only 47 yrs late and it doesn’t work. But hey that’s what this site is all about, and that’s how I roll. Always late to the party, and even then you’ll probably find me in the kitchen 🥳

What the listing said:

Cosmetically in very good condition but does not work. Please see attached pictures to judge condition for yourself.

EBay

Another one with all battery covers! I’m shocked. And what’s that screwdriver there for?

The guy was after £17:00GBP and that included postage, but I put in a cheeky bid and managed to get it with postage for £9:80GBP. Anything under a tenner is good in my eyes.

Here’s some history:

Simon is an electronic game of short-term memory skill invented by Ralph H. Baer and Howard J. Morrison, working for toy design firm Marvin Glass and Associates, with software programming by Lenny Cope. The device creates a series of tones and lights and requires a user to repeat the sequence. If the user succeeds, the series becomes progressively longer and more complex. Once the user fails or the time limit runs out, the game is over. The original version was manufactured and distributed by Milton Bradley and later by Hasbro after it took over Milton Bradley. Much of the assembly language code was written by Charles Kapps, who taught computer science at Temple University and also wrote one of the first books on the theory of computer programming. Simon was launched in 1978 at Studio 54 in New York City and was an immediate success, becoming a pop culture symbol of the 1970s and 1980s.

Wikipedia

From what i can see in the pictures the item seems good, cosmetically. I may be able to see just a little contamination around the battery contacts but I can’t be sure. It worries me when i see a picture that shows a screwdriver alongside the item you are buying, it just screams at me that the seller has been in side and is not being truly honest about its issues. Let’s just wait until it arrives to do a full assessment. I’m genuinely excited about getting this working, as my age veers ever closer to the higher numbers. I need something to stimulate my mind, what’s left of it. 😂

Assessment:

The unit has arrived and on first impressions looks clean and tidy cosmetically. The pads are not very responsive and the battery contacts are seriously corroded. The unit is a power hungry beast, taking two ”D” cell 1.5v batteries and one PP9 9v battery. The unit does not work with its batteries in place, and i’m not surprised really, and to round it all off two screws are missing from the case, and one screw mount is broken. All four plastic springs that sit under the coloured pads are broken, and just to clarify someone has already been in here and it doesn’t bode well. My previous concerns of a screwdriver being in the original photos have been confirmed. It’s been tampered with.

Broken screw mounts and contamination
Bad contacts – contaminated
Pads unresponsive due to broken plastic spring mounts

The board is a typical of many circuit boards from this era that were produced for MB. I had a similar circuit board on this item here: MB – Computer Battleship

Top of board
Underneath the board
You can see the board structure that is typical for this era. The contact points are indicated by the red arrow marks.

In the picture above you will see two arrowed points. These points are the power contacts that make contact with the two seriously corroded battery contacts you can also see above. No wonder there is no power getting to the board. I suspect this might be the cause of our electrical problem.

Repair:

First thing to do is to get those battery contacts cleaned, as well as having a good clean of the main board. This has now been done. I’ve repaired the broken screw post by simply using a rubber washer that has been sufficient for this repair.

Contacts before and after

A friend of mine has kindly offered to print me off four of the “Double Y” springs to replace the ones that are already in place and broken. He owes me a favour or three and needs some subject matter to run through his new 3D printer so I’m very pleased to help him, as pending the outcome I may well buy one myself, as I have been threatening to do so for a while now. This should sort out the issue of the unresponsive pads, first found in the assessment of the item. He’s panicking that they might not be smooth and beautiful, I’ve told him not to worry as they are hidden inside anyway.

What I currently have on the left, what I’m expecting on the right

He’s just supplied me with five double “Y” pieces just in case one is damaged in some way. Let’s get these put in place to see the difference these make.

Out with the old
In with the new

With the new springs in place the pads are working as they were originally designed to, now with some springiness in their operation. The battery contacts have now also been put back in place.

Cleaned contacts back in place

When assembled, the buttons are a little erratic and not always responsive so I decide to look into this further. A quick Look at the board shows that the solder contacts on the board for all of the button connections are worn, the solder has failed so I decide to reflow all these solder joints to improve the contacts. This appears to have worked as the unit when reassembled, now has uninterrupted operation. This is an age related issue. A simple fix.

Old solder joints that have failed and needed re-flowing

Result:

Another 47 year old saved from the scrap heap, it’s been an interesting and sometimes confusing repair and I thank my friend who stepped in to save the day by utilising his 3D printer to make some parts. Without his assistance this repair would not have been achievable.

Looking smart after a quick clean

It’s just another old piece of retro history to add to my ever growing collection and much to my wife’s dismay. Bless her.

Now working

Thanks for passing by, as always it’s very much appreciated.

Forced E-Waste PCs and the Case of Windows 11’s Trusted Platform

I thought this was a very good post from the guys at Hackaday. Most of us who use the Windows platform will have probably come across this issue in the last year or so. Being told your perfectly good computer is not up to running Windows 11 when in fact it is probably more than capable.

Is it no wonder people are moving over to “The dark side” (Linux) in droves….

Until the release of Windows 11, the upgrade proposition for Windows operating systems was rather straightforward: you considered whether the current…

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.

Challenge quiz book and questions
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.

Button removal
All buttons removed
All cleaned and sealed down with Kapton tape

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.

Systema/Krypton – Horizon computerised travel chess set

What the listing stated:

The item has previously been owned before and unfortunately the batteries were left inside to corrode. When tested the computer part does not work.The pieces are a complete set for playing without the computer. Please see photos.

EBay

Systema Horizon
Computerised
Battery corrosion

The unit looks clean cosmetically, and all the pieces are present. The computer side is not working probably as a result of the corrosion that is present in the battery compartment.

So I’ve paid a grand total of £11:49GBP for this unit which is probably slightly above its value. However it was from the St.Helena Hospice in Colchester, so I do not have an issue with this. In fact if I can get it working it will be donated straight back to a hospice I support here in Leicester – LOROS hospice. So all around, everyone benefits. I don’t play chess so it will not be used by me, I believe this unit was originally released circa 1996, so it is roughly 29 years old.

A really simple video, regarding how this unit works

Not much in the form of instructions online, however I have managed to get hold of some pictures of a quick start guide that should suffice for the moment. I’ll try and get full instructions from somewhere. In the meantime, the video above shows how easy it is to setup and use.

Let’s wait for its arrival to make an assessment.

Assessment:

The item has arrived and cosmetically it’s not too bad. There is some writing ink on the lid, and some staining on the base. but nothing that a good clean wouldn’t see to.

Outside good
Inside bad

Open the battery compartment and all contacts are in serious need of a good clean or replacement. Battery corrosion is bad. All playing pieces are included and that’s always a bonus. I do believe that the issue here is purely to do with the acid corrosion, as when tested with a multimeter there is no continuity through the contacts. If the corrosion hasn’t gone too deep this should not be too much of a problematic repair.

Repair:

Now inside of the unit we can see the extent of the corrosion and thankfully it hasn’t reached the circuit board as the battery compartment sits just to the side of it.

Circuit board has no visible issues
You can see the contamination on the rear of the battery compartment

I’ve disconnected the wires from the battery compartment so i can it take it away and concentrate on removing the contacts and cleaning them, or completely replacing them.

Removal of the contaminated battery contacts

The contacts are in such a poor state and so far beyond recovery that I have decided to replace them all. I need two single and three double AAA size contacts. Luckily I do have plenty of these in my current stock.

Prior to fitting the new contacts I will give the entire battery compartment a good clean with some IPA to remove the residual contamination. I will then dry the unit and just use some furniture polish to buff it all up and make sure it’s as clean as the day it left the factory. Once this is done the new battery contacts can be put in place. I can then re-solder the two internal battery wires back into place.

New contacts installed
Batteries fit ok
Contacts checked to see power is a available

New AAA battery contacts in place I just put in the batteries, to confirm continuity with the multimeter. A good 6.4v indicates this part of the repair is good and that the contacts are all working.

Next I’ve decided to replace the two wires from the battery compartment to the circuit board, as the wires, especially the negative one appears very brittle, probably a combination of age and the battery acid contamination.

Two new power wires

I’ve tidied the wire run up by using some Kapton tape to secure it to the shell so there is no chance of a wire pinch.

Before closing the shell up, I use some hot glue to put the speaker back into place.

A bit of hot glue to secure

Now we can get the last four screws in place to secure everything together.

Then switch on…does it work? You betcha, it does everything that it’s meant to, and even though I don’t really know how to play, I do manage to challenge the computer for a good ten minutes. It’s been a great test run and even though I’m not that clued up it is working how it should and is now back in a perfect working order. I’ve created this little video below.

It’s working

Now just a little spit and polish and we can bring this repair to a close.

Result:

It’s polished up well apart from a bit of age staining on the rear, this makes no difference as it’s only the hidden part of the case and every game related part of the unit looks fantastic and it works just fine.

Good working unit, looking superb

Really pleased with this especially as it’s going straight to our local hospice for them to sell on. It was brought from a hospice, and is going back to another, what better way to generate funds for them. I can’t play chess so this unit is wasted on me. Might as well pass it on to someone who’d appreciate it whilst giving some much needed financial support to a most worthy cause.

Another one saved from landfill. Win win all around.

Thanks for passing by and reading this post. It’s always very much appreciated.

Evistr L53 8GB voice recorder

What the listing stated:

Evistr L53 voice recorder – not working, parts only

EBay

It’s not working

I just wish the listings would be more specific, it’s not working because, (Fill blank spaces) you get my drift eh?

The unit looks good physically and cosmetically, and seems to have been well looked after, we just don’t know exactly what’s wrong with it. I’ll do some digging around and see if there are any generic problems, and I’ll also dig out some instructions just in case. It’s another one of those purchases where the cost of the item £2:24GBP has been out weighed by the postage, £2:45GBP however a total outlay of £4:69GBP isn’t all that bad in reality.

Why would you pay more for a used one?

Current prices are in the £30-40GBP bracket. why you’d pay more for a used item confuses me, but then I’m usually easily confused.

I’ve downloaded some instructions, so we can hit the road running with some basic idea of how it works.

Let’s wait for it to arrive and then we can do an assessment.

Assessment:

Well, the box you see in the picture above, was just wrapped in some white A4 paper and put in the post. By the time it’s reached me the wrapping was split and the box hanging out. We are off to a flying start. It’s not the original box as that is for a 16GB version and this is an 8GB version, again no problem but probably used by the seller to beef up the offer.

The unit itself is quite smart looking, clean and generally free from any heavy marks with only light scuffs that you would expect after a few years of use.

It came with an audio connector, and some other bits that allow you to connect it to a phone system to record conversations.

The package as it arrived
On charge

The unit is dead and didn’t come with a micro usb charging cable, however again not a problem as I have plenty of these laying around. I’ve checked the charging port and I’m pleased to say it is in a good state and has no damage. So the first thing to do is to get some charge into the unit as the battery has probably been sitting dormant for quite a while. It was totally dead on arrival.

After a while I have turned it on to see if the charge is being taken and was greeted by this message, not one that I was expecting or one that I really wanted to see to be honest.

Disk Error

Disk Error. My immediate thought is that this is no longer recoverable, however, looking at known faults on their own site I might be able to recover the disk by using a Windows computer to access the disk. I’ll look at that option in the repair section of this post.

Security seal intact

One thing I’m happy with is that the security tag on the back that covers the screw that allows access within, is still intact. I’m confident no one has yet accessed this unit internally. One less thing to worry about.

So realistically it’s a nice neat package in a very good cosmetic condition. It’s only problem that I can see at this very moment is the “Disk Error” issue.

Repair:

So let’s get this unit plugged in and see what we can do. It is really the only issue we have with this unit.

On my computer we have issues though. It’s a windows 11 machine and when plugged in, all the right sounds are made however nothing is recognised. Apparently the drivers for this unit are not supported on this windows system. It can’t see the drive. Damn that’s a problem.

My system
Does all the right stuff but unrecognised

Ok. I’ve had my thinking head on and just had a brainstorm. My brother in law over the road is notorious for not updating stuff. I called him and asked if he’d brought his new computer yet that he keeps threatening to buy and he says, “No, I haven’t Dave“. “Excellent” i tell him, get it warmed up as I’m coming over to use it.

I arrive at his house and he is curious as to what I want to do, I’m always going on at him to update and make his old computer safer, I keep telling him to upgrade it, and here I am asking to use it!

It’s a Windows 10 machine, slow is an understatement but he only uses it for casual browsing to be honest. I plug the cable in and then the recorder, I get a battery charging symbol and that is it. Hmmm.

Another brainstorm, I realise I’m using a charger only USB to micro usb cable instead of a data capable one. Another quick run back to my property and I take back a selection of cables. One of them worked, the drive was recognised and I was able to format the drive but I did it as Fat32. It worked to wipe the drive but I could not get the drive to boot up again without still showing a Disk Error message.

Disappointed I came home, I wasn’t giving up though. I dug out some other data cables from one of my old radio boxes and put it to my computer again, the drive didn’t show on the windows 11 system but it did something to allow me to be able to access the settings via the menu on the unit. I was able to go into settings and format the unit just as it should be via the units firmware.

No Voice records
Here we go, persistence pays off

After the format it indicated there were no voice records available, this was something I hadn’t seen before, we were finally getting somewhere.

It works, just have a look at the video below

All working

There are a lot of settings to play with in the unit. However the recording quality is superb if I say so myself, it’s so clear and balanced. The unit is now fully restored and working just perfectly. Add to that the fact that is cosmetically beautiful we now have a perfectly usable unit.

Result:

Working as well as the day it was purchased, this is probably the best £4:69GBP I have ever spent. A lovely unit, looks good, fits in the pocket nicely and has years of use ahead of it.

A cracking little device

I’ve really enjoyed this little project, it’s been a right challenge and I was determined not to give up on it. I was glad that I persisted and got it working again.

I wonder how many of these units, or those very similar to it have just been thrown to waste, when they were in fact very repairable. Well this one has been saved, and will be usable for many more years to come yet. (And I now know how to fix it, if it ever does break again😂)

Thanks for passing by. Always very much appreciated.

Monty plays scrabble

What the listing stated:

UNTESTED

The product is a vintage Scrabble game titled “Monty Plays Scrabble,” released in 1984. It is a rare find and comes in its original boxed packaging. The game is a portable computer console version of the classic Scrabble game, making it unique and collectible. Please note that the functionality of the game is untested.

EBay

Why did i buy? I don’t know, maybe because its from 1984 and fits my modus operandi. To be truthful i looked at it, saw the wear and tear on it and thought to myself that i can make it look better. It also states it’s a rare find….its not. In good old EBay style its “Untested” which probably means they have put some batteries in, it doesn’t work, so let us use the get out clause of selling it as untested. I could however be very wrong, and just be using unnecessary sarcastic commentary, i suspect it’s very much the latter.

And it has a battery cover. Splendid

Here’s a little history:

Manufactured by Ritam Corp, under licence from J.W Spear and sons PLC 1984

A portable electronic device that plays a competent game of Scrabble. Up to three players may challenge the device. Each player enters one’s own name and subsequently the turn order in which they will play. The players can decide to draw their own tiles or let the device do the randomizing. If the device assigns the tiles, the players may ask the device to suggest a play by using the “Hint” option.

Players keep track of the gameboard using the paper pad provided or use their own gameboard. The device has a LCD readout that is only eight characters by four characters and cannot display the entire board. Players use the arrow keys of the membrane keyboard to scroll around.

All standard Scrabble rules apply. The device will challenge any word played that is not in its 12,000 word vocabulary. The human player is final arbiter however.

The device is powered by four “C” batteries or an AC adapter. Two Advanced Vocabulary Modules were available. Each module added 16,000 words to the machine’s vocabulary to bring the total to 44,000.

Boardgamesgeek.com

And I’m fortunate to have those two advanced vocabulary modules already installed, so this unit has the full vocabulary range of 44000 words. Lucky me. Apparently the unit is able to do 2 million calculations a second, but can take up to 3 minutes to make a move! With a vocabulary built in of 12,000 words that must mean it does a lot of questioning of itself prior to making a decision. I love a computer system that constantly doubts itself, it’s such a human trait.

Anyway, what’s arrived and how does it look. And is it working?

Assessment:

The parcel has arrived and been unpacked.

Fully boxed
All original packaging

Rear of unit

On taking the unit from the box there is no damage cosmetically, the keyboard is a bit dirty and the silver lettering and edging has worn a little.

Great news is that the battery contacts are in a perfectly clean condition with no sign of corrosion

Super clean and the two extra vocabulary modules
Batteries added

With no corrosion visible, I put some batteries in. I switch the unit on and it makes sound, great. Looking from directly above it looks as if there is some writing on the screen but this doesn’t become visible until you move to about 60 degrees away, a bit closer to the base of the unit.

When viewed from above
When views at about 60 degrees away

So the pleasing thing is that it works. In general it is in a very good condition, coming with instructions and playing sheets. As always with items such as this from this time period, there is the expected smell of age induced mustiness, and there isn’t a great deal I can do about this. But I do seem to have a working unit that just requires a little maintenance and cleaning.

Repair:

I’ve had a quick clean of the front keypad and it was quite dirty.

Bit dirty just after a very brief clean of the keyboard

I’m not sure but I might open up the unit and give it a proper wash, I’ve got to have a look at the screen inside as I suspect the screen quality might be improved by replacing some old electrolytic capacitors that I suspect may be around that area. I could however be wrong. Let’s get it opened up then.

The board looks really clean on both sides, all capacitors (and there were only three of note) look good.

Front
Rear

I have taken all three capacitors in the immediate screen area off, I’ve measured them out of circuit and they are all within the 10% tolerance of their indicated ratings so in my eyes there is no issues here. They are working fine.

All capacitors tested and within tolerance

On the rear of the board behind the display is a small variable capacitor. I turned this slightly to the left whilst under power and the screen quality has improved sufficiently be able to view the display from a more natural position. It can’t be adjusted any more though so it is now at its limits, probably a result of its age and limits of performance being reached for that particular component.

The variable capacitor
Improved display performance

To be honest I’m satisfied everything inside the unit is fine, and the slight improvement to the display is more than adequate, I’m now going to close the unit back up and will concentrate on the exterior.

I’ve given the exterior a good polish, and then in my art box I have a silver permanent marker that will be great for touching up the worn out lettering and surrounds, so I will use this just to make the unit look a little more aesthetically pleasing.

Silver pen
All lettering retouched
Manufacturers name now visible
Finished unit

And boy has that made it look better

Before
After

Looking good as new, and with that result we can say the repair is complete.

Result:

We now have a good looking fully restored and fully working unit. It looks as good as the day it was sold and still does what it was made to do. The screen is at its limits but should last a good while yet. A smart looking 41 year old unit that has been saved from the scrap heap and will be around for a good time yet.

All clean, look at the restored lettering

Here we have a small video of its basic operation

Easy to operate even without instructions

All in all another satisfying repair, and yet another item saved from landfill. If it’s damaged, 9 times out of ten it can be repaired and reused. We don’t need to be so wasteful.

Thanks for following the repair, it’s always very much appreciated.

Thank you 🙏

r36s.co.uk

I’ve managed to secure this item for an all in price of £16:25GBP and thats including the postage. The seller had a number of these selling, I suspect they are customer returns as they still have screen protection, they are in original boxes with stickers on them, and that makes me suspect they are returns.

I think I may have paid over the odds for this unit.

The fact that as soon as this batch were purchased, another set had taken their place on the selling platform confirms this. On the r36s.co.uk site, these consoles retail at around £65:00GBP, you can get similar items from other Chinese outlets that are considerably cheaper. This is an emulator unit that runs via the Linux operating system, and is supplied ready installed with around 15,000 games already on the unit utilising a number of gaming system platforms. As the operating system is open source, you can also add additional games should you wish to do so. The one I have purchased is stuck on just the one particular game i believe. I think I have some work to do.

I very much suspect the issues with this unit lays solely with the software and are not in anyway hardware related. I could however be very wrong. My knowledge on these systems is very limited so I’m going to be very reliant on information and tutorials that i can find on line.

And i may as well download some operating instructions prior to its arrival, just to be a step ahead and furnished with the most basic knowledge of its operation, maybe then i won’t come across as a totally clueless clown.

Assessment:

It’s arrived and cosmetically it’s fine. It just doesn’t work. It doesn’t even do what is stated in the listing. More EBay untruths.

Looks nice. Just doesn’t work

Powers on, charges ok and that’s about it. Box looks nice. Finding it hard to talk of anything else positive. Oh, and it’s not an original it’s a clone machine… cheapo copy. Any way, let’s have a look at getting it to work.

Repair:

So first thing was to download a new OS for the unit, unzip it, and download it to the removable sd card, easier said than done. I think I’ve probably lost all the games that were installed, but without a system to run it all, what’s the point. I can always download games later, I have however backed up a number of files as suggested so let’s just wait and see.

Trying to prepare the new volumes on the drive

The first operating system downloaded did not work, because now I’ve been informed that this machine is one of many clones out there, it’s not original. Lovely. Not a problem, we can still get another operating system, it’s just going to take a bit more of my time to do so, and god knows how long it will take to download the games. This is the biggest pain in the ass with these systems, the sourcing of the programs to ensure the system runs smoothly.

But it will be repaired. And I’m in no rush. I’m off out for a while.

I have had to download an alternative operating system ArKos_K36_v2.0 to my computer. It then has to be run through a disc imager programme to prepare the disc and install the correct partitions and system information, onto the micro SD card used by the unit.

That all done, time to plug the card into the unit and see if it turns on.

Hallelujah! It works.

The operating system successfully installed

Having to format the original card obviously erased all the games that were originally on the card. There were around 15000 games on this unit, but let’s be honest most of them would have been games that were either inferior, similar to others, or just used to bloat the card out. I’m now in a position where I can be choosy about the games I load on the system, and this will allow me to not have it so cluttered.

This is where it gets a little more tricky.

There are a number of people and sites I have spoken with or looked to, to find out the information required to carry out these tasks. And for someone who hasn’t messed about with computer and program files and structures for many a year it is quite daunting to say the least.

I have downloaded a file that is recommended and contains many of the 15000 games originally on the card but with a lot of the bloatware removed to make it a more structurally pleasing and easier to handle package. It’s called the Tiny best set go package and is downloaded from GitHub.

These games are broken down into Rom packages and have to be removed from the download and placed into the easyrom folder on your operating system, it’s a little more complex that that but that is the crux of the task. I won’t go into finite detail as it will bore your asses off and there is plenty of information on how to do it already out there.

I will recommend this one guy as having a superb little site regarding hand held consoles such as this and their issues: Handheld database

Anyway the task has been completed. I’m probably not going to get involved with such time consuming repairs as this again. It’s been a learning curve, but just too time consuming for me. I’ll leave these issues for the younger generation.

Result:

It works. It’s been saved from landfill and there is no better outcome than that. To be honest it’s unbelievable that so many games and so much information can be held on such a small memory card.

Space invaders….im now content

In general the game quality is really good, only let down sometimes by the way that the emulator software interprets the program in question. There is more than enough on here to keep anyone occupied during some downtime. There are many classic old school games on here that will also keep the old farts like me amused as well.

Overall it’s been a tough repair, I pretty much knew from the start what the issue would be and went into this repair totally blinkered. I have learned a lot from it, but will I be working on these again? I doubt it unless one of the younger members wants one then I might have another go. But until then it’s job done, another bit of throwaway hardware saved from the scrap heap.

Edit: I couldn’t keep away could i? I found a chap local to me who works on these units, and he has kindly offered to assist me if I should ever need anything clearing up. Well I couldn’t resist that offer and in two emails he has shown me just how to get these games downloaded, it’s simple when you know how.

19939 games now. Blimey.

So simple that rather than download a few games I’ve gone a tad over the top and now have 19939 of them. That should see me right beyond my natural existence and into the afterlife. What a lovely fellow. There are still lots of nice and helpful souls around.

Success.

Thanks for passing by, it’s always appreciated.

Nintendo Gameboy Printer

What the listing stated:

Listing for a FAULTY Nintendo Gameboy printer unit.

The printer is FAULTY, it has a lot of battery leakage in the battery compartment, so doesn’t currently power up. Some of the terminals look like they should clean up pretty well, but i cannot guarantee. 

As it doesn’t power up, i haven’t been able to test it. So can’t guarantee thats the only issue.

The casing has some discolouration, marks and other imperfections here and there.

I haven’t attempted any repairs and cannot guarantee it is fixable. 

SOLD AS FAULTY/spares/repairs.

EBay

Here are the supplied pictures:

Serious yellowing, good candidate for Retrobrighting
Some serious battery leakage contamination

I think I’ve got my work cut out with this one. It’s another piece of unloved technology from 1998 looking for a new life. I’ve paid a total of £19:89GBP including postage for this item, probably at the higher end of what I’m comfortable with for an item in this condition. It has some serious corrosion issues that could go a lot deeper than just the battery contacts. There is a definite issue with discolouration, however I’m happy with that as it will be my guinea pig for my first attempt at retrobrighting, this process i discussed in this post a few days back: Retr0bright – What’s that then?

My plan of attack for this unit is to completely dismantle it, give it a thorough clean, retrobright the casing and then attend to the electrical / component issues.

Here’s some history about the printer unit:

The Game Boy Printer, known as the Pocket Printer in Japan, is a thermal printer accessory released by Nintendo in 1998 which ceased production in early 2003. The Game Boy Printer is compatible with all the Game Boy systems except the Game Boy Micro and is designed to be used in conjunction with the Game Boy Camera. It also prints images from compatible late-generation Game Boy and Game Boy Color games. It runs on six AA batteries and uses a proprietary 38mm wide thermal paper with adhesive backing, originally sold in white, red, yellow and blue colors. In Japan, a bright yellow Pokémon version of the Game Boy Printer was released, featuring a feed button in the style of a Poké Ball.

Wikipedia

If I manage to get this into a working state it will be added to my GameBoy collection.

I just need a suitable lead to connect between the console and the printer, and a small roll of 38mm wide thermal paper. I’m currently sourcing these.

Assessment:

Well it certainly has the yellowing issues and I will cover that in a separate post where I will have my first attempt at Retrobrighting the unit. With batteries in place, the unit is very dead and no matter how many times the switch is operated, it remains dead. Battery terminals are a mess and there is a lot of evidence of battery leakage and corrosion.

Serious yellowing over the years visible at all angles
Serious corrosion across battery terminals

The board inside hasn’t been that badly affected by the corrosion, however one track from the battery terminal was showing signs of decay and will need attention. There are parts of the board that will need reflowing as there are some dodgy looking solder joints.

The main board
Motor removed
Signs of corrosion by the battery terminal

I’m happy that all the issues have been identified and I do actually have the items to carry out the repair. I will focus on the external issues such as the yellowing before dealing with the contacts and main board issues. Stay with me now, the repair begins.

Repair:

The Retrobrighting process for the shell assembly can be found in a separate post here: First attempt at Retrobrighting.

Wow

Needless to say the results are fantastic and I shall look at incorporating this method into more of my future projects. I have since given the case a second treatment and it is pretty much perfect with no sign of discolouration.

As you can see in the pictures above, the battery compartment suffered from some severe acid contamination. Using a grinding pen and a lot of cleaning solution, three of the five contacts were saved but two were beyond repair and I had to replace these with new contacts.

Replaced contacts
Grinded and cleaned.
Battery contacts were so poor only three of the five could be saved with the other two requiring new replacements

I then loaded the battery compartment with new batteries and then checked the two terminal ends to assure continuity, this was confirmed and continuity exists throughout. As a result the battery issues and power supply have now been resolved.

I mentioned that one of the tracks on the main board was showing signs of corrosion. I filed this down, cleaned it, and then brushed the board down with IPA and checked the continuity and this was fine. All suspect solder joints have also been reflowed, they are all looking good and new.

Track issue in the top left area by the battery contact. All corrosion ground off and cleaned with IPA
Area of concern highlighted on the left side picture. All attended to and cleaned and recoated with some solder mask to prevent any further decay

I had previously removed the motor from the board to assist with cleaning, as i didn’t wish to damage any of the ribbon cables. I then reconnected the cleaned and freshly repaired board, to the restored battery compartment to see if anything lit up. It sure did.

We have a light

This was pleasing as it now showed that we had continuity from the battery compartment to the board. I then added the motor back in and we also had some movement.

Movement restored

This again was very pleasing as everything we have done so far seems to be working. However it proves nothing yet until I can get the correct cable and some correct sized thermal paper to see that it actually does print, or even advance the paper. Those items are being sourced, and I don’t want to jump ahead of myself just yet as there could still be a number of yet to be addressed issues that may arise. It’s very much a fingers crossed period until we can test the unit properly.

Let’s clean all the other plastics whilst we await all the other items to be attended to.

All washed and drying out

Now we will commence reassembly.

After with light visible
All restored, working and looking pristine

Now all assembled the motor moves into position when turned on, the feed button also works. The paper rolls for these units are at the moment extortionate and selling for about £10GBP for the tiniest of rolls, and I’m not paying that. I have a thermal printer at home and I have cut some of this paper to size to test the transport, and this works just fine. Just awaiting the cable to connect the GameBoy to the printer. Fingers still firmly crossed.

Result:

I’ve just found out that if you hold the feed button whilst turning on the unit you get a test message. I’ve done this and I’m pleased to say the unit is fully working.

It’s working perfectly

I’ve also connected it to my game boy and the game – Pokemon pinball, and was able to print off the high scores. It truly works.

High scores

I’m just so pleased how this project has gone. It has been a complete refurbishment, clean, and I have even managed to reuse the original stickers. The unit looks pristine and really is a nice piece of kit. This goes into my GameBoy collection and has many more years of good use left in it.

Clean and tidy
Total refurbishment

And to think this would have probably ended up in landfill. Scandalous. The cost of repair to me has been less than £2GBP and the majority of that was for the peroxide solution to do the Retrobrighting.

Great result. Very happy with this.

I can now uncross those fingers. All is fine.

Thanks for passing by, as always most appreciated.
