Exec Helper 8200 electronic organiser

What the listing stated:

Good condition – with instructions and original box

EBay

No beating about the bush, straight to the point. No messing. Cost me the grand total including postage of £9.94Gbp

What? You’ve never heard of it? Have a google and I think you will agree there is very little information anywhere regarding this unit. There may be a few items on eBay, where you will see a couple on sale (normally faulty) for a very reasonable price, however all are missing two very important items, a box and instructions, the latter being as rare as hens teeth.

I’m fortunate to have an excellent example now, with both with only one polystyrene insert and not two, a box and instructions. They call it an organiser, that really is an overstatement, because if you read below you will see it is a really difficult unit to get to grips with. However it can be done, it just takes patience. The unit has three functions that are: Dictionary, Address book and Calculator.

This isn’t a repair video. As there is not a thing wrong with it, it’s absolutely cosmetically perfect. It just requires you to read thoroughly through the instructions, if you are fortunate enough to have some that is, and in this instance I can be very smug. I do have those original instructions, and there are probably more copies of the Magna Carta out there than there are instructions for this unit, or so it seems.

This video was from a chap, who posted it on YouTube a couple of years back. In the video the presenter had no instructions to follow. He also knew nothing at all about this unit. Its origin, age and use was a mystery. Using the Exec Helper 8200 can be both perplexing and frustrating.

What it does

Dictionary

One of the main features of this unit is its dictionary function. Users can Type in a word and press enter to retrieve its confirmation as a valid word. However, the device does not provide definitions or additional information beyond confirming the existence of the entered word. While it does allow scrolling through words, the lack of comprehensive definitions limits its utility as a traditional dictionary. Additionally, any misspelled words will not be recognized, resulting in a “not in memory” message.

Address book

The address book feature of the unit offers the potential to store and search for contact information. However, the functionality of this feature is somewhat confusing and not user-friendly. Users are prompted to enter a name, but pressing enter does not submit the entry. Instead, a separate search button needs to be pressed. The device’s scrolling and next line buttons suggest the ability to store multiple addresses, but the precise method of doing so remains unclear. Overall, the address book feature of the unit lacks intuitive design and may frustrate users attempting to utilise it effectively.

Calculator

In addition to its dictionary and address book capabilities, the unit functions as a calculator. When numbers are entered, the device immediately switches to calculator mode, allowing for basic mathematical operations. The calculator feature includes memory recall, addition, subtraction, percentages, and other commonly used functions. Unlike the address book and dictionary functions, the calculator feature of the unit appear to be straightforward and functional.

Date of manufacture?

The exact release date and availability of this unit remains uncertain. Judging from its design and styling, it is likely that the device originated from the late 80s or early 90s. However, due to its scarcity, finding a working unit or acquiring one in boxed condition can be challenging. I struck lucky with this one.

That said it probably was once a mass produced piece of tat that failed so miserably, that everyone who owned one threw them away, before they could ever be associated with owning one. They were that bad….or were they? I don’t know, there is so little out there about them that you can’t really make a reasonable judgement or gain constructive feedback regarding them.

It was probably a unit that was killed off in its infancy by one of the bigger names that were starting out around the mid 80’s that had a better, product and presence at this particular time. (Psion for example) A simple case of being in the right place at the right time.

Or is that the right place at the wrong time?

Edit: I have done some digging around and it seems to be that these units were sold via the UK newspaper “The Daily Mail” as a reader offer. I even have the original return form for it however there is no sign of a date. The only thing that ties it to the 90s is that refunds can go either to “Access or Visa. The Access “ Your flexible friend” card ceased in 1991 when the banks involved started doing their own card transactions. So it was definitely very early 90s maybe even late 80s. I’ll update this post if I uncover anything further.

Stylophone portable organ – you were warned

Earlier in January I posted that I’d brought this retro pocket organ from EBay. Stylophone pocket organ It has now arrived and wow, it is in near perfect condition, the seller did not lie when stating it hadn’t been used since 2008. It is almost mint.

Anyway not being a person to disappoint anyone, I did promise that I’d video myself learning to play the unit. I wanted to prove that anyone can play these “Toys” that were hugely popular over the last 40 years. You lucky people. Here’s the video below.

Enjoy.

Samsung SQ3000 electronic typewriter – assessment & repair

This is the follow up to a recently obtained electronic typewriter that was purchased in January 2025, the initial post can be found here: Samsung SQ3000 electronic typewriter.

The following post will deal with the assessment on its arrival and what I am going to try to do, to get it back working again, as close as possible to its original state.

I’ve downloaded an instruction I manual, I’ve had to download one for a Smith Corona Wordsmith 200, it is in theory the exact same unit, just under a different manufacturers branding.

Assessment

It’s arrived and apart from a little age yellowing it looks ok. There is a PAT testing sticker that says it was last electrically tested back in 1998 and is due a retest in 1999. This corresponds with my date estimate of mid 90s.

I will retest and renew the safety checks when I’m finished working on it. I have noticed that the paper bail/release rail is broken on the left hand side so I will have to add that to the repairs, this shouldn’t be a major concern.

Before I took the roller out to get to the paper bail I did start the machine up. Everything went as expected and when I tried to type I was getting some weird reactions to the keys I was pushing. All kinds of characters were appearing.

I checked the daisy wheel and there was a click. It wasn’t sitting right. I reset the machine using the two reset buttons and the machine then went through its reset programme, pretty much the same effect as turning it off and on again. (Not much changes in the way of tech there then)

Well that’s worked fine, I have tried every combination on the keyboard including the erase function and this is now fully working. It really was quite simple. My next job is to try and fix this paper bail.

There is quite a bit of dust and dirt inside that needs removing. And whilst I’m at it I will lightly re grease the areas that need it. Let’s be honest it’s not been done in the last 30yrs so now is as good a time as any. Inside will get a light hoovering and a bit of a tart up, I’m not going to go mad. I will clean the outside and all knobs and buttons and try to get rid of some of the yellowing, but to be honest as long as it’s clean I’m not too worried about age marks.

The keyboard has lost a few of its letters. I will remove what is left of some of them and use some keyboard decals to replace the missing ones. This will be one of the last jobs I do.

Well that’s the assessment done and apart from a few small issues and requiring some basic maintenance I don’t think we have an immense amount of work to carry out. We know it now works. Let’s hope I don’t cause any further carnage whilst working on it.

Let’s get to work.

Repair

Right it’s straight onto the paper bail to try and fix the snapped end. Firstly I’m just going to use some superglue to get it in place. When this is dry I’m going to create two “Doublers”, place one either side of the damaged part and glue these in place to create a stronger repair and to add some stability to this area.

I’ve got some black semi rigid plastic. I’ve created a small template from a tracing that I did of the good right hand side of the bail.

I now have two doublers cut from the plastic that I will use as explained above.

It doesn’t matter that they are not perfectly shaped, however they both fit perfectly well into the profile of the bail arm, and this portion of the arm is hidden in the typewriter housing anyway, so the part will not be visible, but it will now be strong.

The Doublers have been put in place using a quick set epoxy resin, I will leave this to dry for a good few hours before I tidy it up, with a light clean, and then I will try to get it back in place.

Bail arm repaired, installed and working.

Now that’s done i’ve gone inside and there were a nice couple of spider webs around the transformer that are now history. I’ve secured the cable in the rear of the unit that never had any tension restraint, so that there will be no issues, should anyone now give a good yank on the cable lead. This is a safety addition I have made that was never on the original unit.

Cable restraint screwed to base to prevent strain on internal wires in and around the transformer bay.

I have also tightened all screws and checked the wiring and this all seems ok. Plug and fuse have been checked and all is looking good. I’ll carry out a PAT test once I’ve finished the clean up.

I’ve cleaned the main roller with alcohol, and removed all the old grease and dirt from the platten adjuster switch and the roller advance knob. I have removed the platten plate as well as the six mini rollers that are here. I’ve cleaned them all and re assembled/installed them.

I have cleaned the daisy wheel as well as in and around the printing head unit.

Inside the unit I have given a good hoover as well as a light clean and again removed more old grease. I have given the exterior plastic a preliminary polish, this has removed some of the yellowing and made it look “cleaner” I am not going to worry too much about the yellowing as it isn’t that bad, and I don’t really want to venture into carrying out a “Retrobrite” on this unit. It would take too long and there would be no benefit for this project.

I’ve now added very small amounts of a watch lubricant to those areas that i have previously cleaned and removed the old grease from.

The unit has been reassembled and I’m pleased to say it is still working fine. It’s running smoothly and all aspects of the unit seem to be working just fine. To be honest it seems to be printing clearer to me.

Daisy wheel and print quality is perfect

I don’t know how long the print cartridge has been installed but I suspect it may have been a few years back. It’s almost finished, and I do have a replacement on order. I’m sure a fresh cartridge will make the print stand out even more.

Next I’m going to have a go at replacing some, or even all of the keyboard letters. It all depends how it looks when I start replacing them. I’m going to gently rub off the lettering that is left and clean the keys using a 95% pure Isopropyl alcohol solution (IPA).

All damaged and missing key decals removed in preparation for replacement new decals. Others may have to be removed dependant on how the new ones look when in place.

These are the replacement key decals I will be attempting to use.

I’ve replaced the damaged key decals. The ones I’ve used are a lot brighter than the original ones and really accentuate the yellowing. I’m not troubled by this as it keeps its “Old” look. I would have to scrape and wipe for hours to remove all the other keys and to be honest it would look just like someone had gone abroad to have a bright white set of dodgy veneers installed, it would look quite out of place, and in your face. Just like a Cheshire Cat smile.

It serves a purpose and just allows the unit to be usable again.

The final product:

Fortunately a lot of the equipment and parts I have used, I was already in possession of, so there are no additional costs for this project. Below you can view the total costings for this project as they currently stand:

Purchase inc postage £13.14
Cable restraint £0.25
Keyboard decals £1.25
Total cost of project £14.64

Again I have managed to save a fantastic 90s retro item from landfill for very little cost, and that is a fantastic result. It has years of use left in it, as long as the consumables remain available, and of that I am confident that they will be available, for at least the next few years. The unit is clean, I’ve just carried out an electrical PAT test and it is electrically sound.

Believe it or not I’m going to go back in time and will write some traditional typewritten letters to friends and family. I’m looking forward to doing that and it will certainly surprise them, it will be totally unexpected.

When all that is done, i will donate this unit to our local LOROS Hospice shop so they can sell it on and raise much needed funds. They deserve it. Edit: This was done in March 2025 at their shop in Hamilton Leicester. I hope it gets them a good price.

Watch the brief video for the final words on this restoration. All 13 seconds of it.

And that’s it folks..

Thanks for passing by.

Samsung SQ3000 electronic typewriter

What the listing stated:

Offered here is a good vintage Samsung SQ-3000 electronic typewriter. It powers up and operates when the keys are pressed. However, the symbols printed do not match the button pressed ! The daisywheel may be out of line. Otherwise, good cosmetic condition. Any questions, then please ask.

EBay

I have again succumbed to purchasing something very retro, a typewriter. Yep it has a fault just as most things I buy have, that’s part of the fun of it all, can I fix it and save another item from landfill? Who knows but I’ll give it a try.

This Typewriter, the SQ3000 was also sold as the Elite S-7500, Hanseatic Europa II, Leader MD, Olympia Textstar MD, Opperman S-7100, Privilege Electronic 2600, Royal RT 7700, Silver Reed EX-133 MD, Smith Corona Wordsmith 200 and Welco EX 260 DS. It was manufactured sometime between 1990 -1995 and was a mass produced low cost typewriter of the time. Personally I think it was around 1995 as this was when regulations insisted that electronic items such as this required wired in power supplies, and this unit is a hard wired unit.

Samsung loosely translated/stands for “Three Stars”Apparently the three represents “Something big, numerous and powerful” and the “Stars” represent “Everlasting and eternal” so there you have it, that is today’s history lesson.

I loved using typewriters prior to the word processor/Pc rendering them useless. There is just something special about them, I can’t quite put my finger on it.

This item looks to be in fantastic cosmetic condition, and I have also checked that the consumables are available, they are so I might have struck lucky. From what I can see in the pictures a number of letters have worn off the keys, hopefully I can source replacements, or decals or I may even repaint them myself.

I have had to download the instruction manual for the Smith Corona Wordsmith 200 as it is the exact same unit under a different name, Samsung just don’t seem to have anything listed or historically available for download.

I think I’ve bagged a bargain (if I can get it working) I’ve paid a grand total including the postage of £13:14 GBP and that was after knocking the seller down a few pounds from the original price. He bit my hand off to be honest, so we’ll just have to wait and see what arrives. If all else fails I can certainly use it for spare parts in the future.

Anyway, this now gets added to the long list of other items I have, that need to be repaired. Please check back to view the “Assess and repair” post that will follow, explaining what arrived, its condition and what I will be doing to get it back in working order.

Thanks for passing by.

Stylophone pocket organ

What the listing stated:

A BRILLIANT RE-pro of an iconic Stylophone Pocket Organ from 1968.

Bought for me as a birthday present back in 2008. I packed it away and placed it in my loft.

I’ve just found it again and have added 3 Duracell Plus AA batteries to test it for the first time. (Included in sale)

All works extremely well.

The unit is as new, the box has very minor wear.

EBay

We will just have to wait for delivery to see just how true this listing is… however I have spoken with the seller today, he’s a lovely chap and my mind is at ease that this is a genuine good purchase.

Anyone that pays the slightest bit of interest to my blog will know I love retro electronic equipment, especially if at sometime in my life it has meant something to me. Well, the Stylophone was a very basic synthesiser/toy that popped its head above the parapet originally in the late 60s, but was super popular in the mid 70s and that was when I first got my hands on one. It was a cousins unit, not mine as my parents wouldn’t pay out for toys like that as they were just a fad. (How wrong were they?). So envy struck once again as I was never able to have one…..now fast forward 50 years and I’ve now purchased a good example of one.

The Stylophone is a miniature analog electronic keyboard musical instrument played with a stylus. Invented in 1967 by Brian Jarvis, it entered production in 1968, manufactured by Dubreq.

Some three million Stylophones were sold, mostly as children’s toys, but they were occasionally used by professional musicians such as John Lennon, Kraftwerk and David Bowie.

Wikipedia

Back in the day a chap called Rolf Harris was constantly on the TV advertising or playing these units, however the less time talking about this fellah the better, he was a right wrong ‘un.

This particular unit is not an original, I’m still after one of those. This unit was a reissue in 2008 so it’s about 17 years old now. But I’m happy with that. And it works, and for me that’s unusual as I normally only buy broken ones to repair, maybe the original one I’m after will fit the bill, if I can find one that is not completely overpriced. The original unit ran off a single PP9 9v battery, these newer units have improved circuitry and operate off 3x AA type batteries using half the original power. I’ve said before retro electronics are rapidly become the antiques of tomorrow, and people are out of their heads with the prices they are demanding even for something that is completely wrecked. They all need a reality check for the prices they are demanding. The total I have paid for this one is £20:00 GBP and that includes the postage and batteries, so in all I think I’ve got a bargain if it matches the actual listing.

I’m actual going to record a video of learning how to play this unit, just to see how easy or hard it is, and this creation will also be the subject of a later post, Here: You were warned

In the meantime prepare your ears for an assault to the auditory system as someone with no ability to hold a tune tries to play a toy/instrument from the 1970’s, you are truly blessed 😂

You lucky people 😂

Namco arcade classics tv plug and play games joystick

Here’s what the listing stated:

FAULTY no power, NOT WORKING for Spare Parts or Repair.

TEST NOTES: Does not power up, no further testing, unable to check any functions. Battery leakage with corrosion in and around battery compartment.

Ebay

Another low priced item that I fancy getting working. And as is standard with me it has corrosion. This item is from 2003, it is a self contained game arcade system that plugs into the tv. It has five games installed including classics such as Galaxian and PAC Man, so compared to some items I’ve purchased of late, at 21 years old this one is a relative baby.

Well, we now await its arrival where we can give it a good look over and assessment. Hurry along now delivery person…..

It’s arrived.

It’s in pretty much perfect condition, all stickers are in place and it hasn’t been previously opened.

I’ve put in 4 new batteries, and damn it. It powers on. It’s working.

I’ve plugged it into the back of a television and it also plays.

Yes there is a little corrosion on the battery springs but I’ve seen a lot worse. I’ll give these a little clean just so I can say I’ve done something.

It’s quite rare these days to get a bargain off of EBay, and for the seller to be truthful in his description, in fact he’s been exceptionally honest, just writing it off without testing. A big bonus to me.

As the saying goes, if it ain’t broken, don’t try to fix it.

Makes a boring post though, sorry about that. A bargain, yes, and another one kept from the tip and will be used at home in the garden pub, the wife will love this as she’s a big Pac-Man fan.

Result!

A bit of this and a bit of tat

If you were going to open up a shop, what would you sell?

I miss the stores such as Maplins (aka Radio Shack). When I used to go into town with the wife at the weekends she would go do her thing and I would go into and spend a lot of time in Maplins. For her it was like a kind of Man Crèche as she knew where she could easily find me ( don’t forget this was in the days when mobile communication was in its infancy)

Here you could buy individual electrical components, it must have been murder doing a stocktake. But I loved it. All the kits, all the ideas, and all the boys toys you could dream of.

I really miss Maplins.

I’d also love to have a store where you could get hold of good quality retro games, and equipment at a reasonable price, not at rip off prices that are currently being seen on auction sites. People really do have inflated ideas of the worth of items only a few decades old, they really are becoming the new antiquities.

So maybe the shop I’d like to own would be a mix of Maplins and a quality second hand store of memories. Somewhere the hobbyist or dreamer could walk into and spend a good while reminiscing, and maybe buying some stuff.

That would be nice.

Bambino kick the goal football game

What the listing stated:

We have tried a few batteries but the unit does not power up so beig sold for spares.

EBay

I obtained this for a very reasonable price considering the amounts being charged these days for similar battery operated 1970’s items.

This unit was assembled in 1979. From initial pictures a few things are pleasing. It looks fairly tidy, the battery cover is supplied, there appears to be no corrosion and the labels appear intact. However actual delivery and when it appears in my own hands may prove otherwise so I’ll await its arrival to give a final judgement.

Well the item has arrived and considering it’s 45 years old it appears to have had a good life. A few small knocks and scars, no more than what you would expect….lets get some batteries in and see what occurs.

A few cold solder joints needed re flowing

Inside is amazing, no LED screen just a tube that looks like an old Cathode Ray tube that you’d have on a TV. (Actually known as a Vacuum fluorescent display) Thank god this isn’t damaged as it would be game over. Wiggling a few contacts and I can hear the speaker crackling, closer inspection shows some cold solder joints so I quickly reflow these and it all springs into life. Excellent.

Lovely old display- more like a cathode tube

I’ve decided to take it all apart and give the parts a good deep wash in some soapy water.

I’ve cleaned the two switches with a contact cleaner, I’ve cleaned the screen membrane and all buttons and their attached membranes as well.

The whole shell has also been cleaned in all the nooks and crannies, and it looks superb.

Now assembled it is in full working order, everything works as it should and the display is bright. The batteries are a tight fit but that’s not so much of an issue. Once you get into the game it’s quite addictive as single player mode is a right challenge as the computer is a great goal keeper 😂

Just can’t score – computers goal keeper is too good

Again it’s been quite a simple fix but an enjoyable one. It’s always good to see something that is about to be disposed of brought back to life and saved from the landfill. I paid a total price of £12.71GBP for this unit, and items of a far worse condition are currently selling in excess of £40GBP on EBay. However this is going into our games box in the garden pub for use by the family, especially the kids who I hope will appreciate the height of technology we had in the 70s.

Tiger “Sonic the Hedgehog” handheld console

What the listing said:

Console is sold as nonworking, shows no sign of life. Item is in good physical condition but there is a lot of corrosion in the battery compartment

Ebay

I’ve decide to look into what seems to be the “New Antique” sector of retro gaming. The prices being commanded for 1980s/90s old school gaming is crazy with many small handheld items that would have cost a couple of pounds being sold into the hundreds. Absolutely nuts!

My decision making process on this was simple. I love hedgehogs, we have plenty of hedgehog visitors to our garden, so what better game than “Sonic the Hedgehog?”

Anyway, at the cheaper end I managed to bag this for £9 GBP. If I get it working, those units are selling between £20 – £45 so I should at least get my original outlay back, pending on what work needs doing.

So here we go….

Well, it’s arrived and cosmetically it looks fine.

Now I opened the battery compartment and could see no corrosion, on opening further I noticed some of the screws had been threaded so I guess someone has been in here before me. And I was right. The corrosion can be quite clearly seen on opening the unit.

Where the corrosion is on the negative terminal, a wire is also disconnected, hooray I thought, an easy fix. Hold on tiger, it’s not that simple. it appears the corrosion has leaked down the wire to where the negative wire joins the circuit board, in fact all four wires at this point are holding on by threads of wire. These will need re soldering.

This game appears to be from 1992 according to the stamp on the main board.

The negative terminal connector is broken, i have some replacements on order but I’m going to repair this one.

I’ve taken the corroded rivet out that held the spring. I’ve found a small screw and have used this to connect to the plate. I’ve cleaned the whole lot with wire wool and have cut off the excess screw and filed it all down. It now looks as good as new and no cost involved. I will finish it off with a dab of solder on the back to ensure good contact is maintained.

Peering underneath at the board it all looks ok, needing just a good clean with IPA. However, I’m not really going to be able to confirm this until I’ve re soldered and checked continuity from the batteries.

There could be some damaged tracks, again I’ll know that when all the basic setup and tests have been done. There is also a possibility the speaker could be damaged as the corrosion has reached there. I’ll test with the multimeter in the meantime. That all checked out ok and the speaker is fine.

I’ve given a good overall clean with some IPA and the entire unit inside and out looks as good as new.

I’ve replaced both the power cables from the battery unit as one had fallen off and the negative one had looked as if it had been crushed. I was changing so it made no odds to change the other.

I ran some checks with the multimeter and everything is fine, all tracks are good and it looks as if the corrosion was localised, this unit has dodged a bullet.

Batteries in and it’s now working well, see this video short:

When you don’t know what you’re doing

However, as I’m not a gamer I have absolutely no idea what I’m doing, it makes a lot of noise and appears to work but god knows what I do. It certainly does a lot more than it did when I received it.

Another one saved from landfill.
