The Memotech MTX Series

 

Memotech Sales on ebay UK

2011  2012  2013  2014  2015  2016  2017  2018

This page had gotten to be far too large, I have now reduced the number of items on this page to the last 12 months or so, other items have been archived by year.

 

Despite their limited success in the 1980's, there seems to have been an upsurge in the popularity of Memotech machines with the "retro" computer community in recent years. I have started to keep track of the items coming up on the UK ebay auction site - you may find that this information is a useful guide to the price you can expect to pay if you are looking to pick up a machine from ebay or elsewhere.

I am not sure how long ebay keeps expired items live so I have grabbed a copy of the main advert's photo, along with a brief description and details of the sale. Items with a "sale" price marked in red, were either not sold or the item was ended early.

I will try to keep this page up to date, but will only create new entries after the listing has closed, in the meantime, . . . . . . . .

Check if there is anything from Memotech on ebay UK at the moment

Some simple, and probably obvious buyer's tips . . . .

  • Do you want functional machine or a "collector's" specimen? If you are looking for a model in pristine condition with all of its original accessories in the original packaging, you can expect to pay significantly more than for a working MTX. You are not likely to get a boxed, "as new", machine for much under £200, whilst a functional machine, with power supply, will probably be around £100-£120.

  • Be aware that MTXs are not always "what they say on the tin", for example, an "MTX512" that I bought off ebay has only 32k of RAM, i.e., the case actually houses an MTX500 system board. If the machine is advertised as working, you could ask the seller to do a simple check to determine how much memory is installed.

  • If one is not already shown in the listing, always ask to see a picture of the video/TV output, even just showing the "Ready" prompt. Failure of one or more video RAMs is a common fault, indicated by corrupted characters on the screen. (The fault is relatively easy to repair but requires replacement of one or more of the VRAMs which are not in sockets, soldering is required.)

  • Unless you already have access to a suitable power supply, which was normally provided by the Memotech external transformer or from an FDX system, you will have difficulty sourcing a PSU separately. Be aware of this if you choose to bid on a model with no PSU included.

  • The majority of adverts include words like "Vintage" and "Rare" - Binary Dinosaurs has an interesting and amusing take on "retro" computer adverts on auction sites here.

  • Whilst obviously far less common than a ZX Spectrum and the like, MTX500/512s do come up regularly on ebay. Other models such as the RS128 or MTX512S2, along with Memotech peripherals are much less common.

The chart shows an overview of the sale prices for MTX computers on ebay UK between 2011 and June 2017, the chart is based on working MTX500/512s, sold with a PSU and does not include postage & packing charges. It takes no account of condition or other items included in the sale. The two "outliers" were an MTX500 (£451) and an MTX512 (£536) sold in February 2013, both were boxed and in good condition, but no better than others sold at much lower prices - for some reason, the "market" appears to have had a temporary blip that month.

I find that the prices on ebay bear little relation to the quality of the MTX and have more to do with the luck of the draw. For example, the final auction price for two MTXs, sold around the same time and which might appear to be in the same condition, can be under £100 for one and over £200 for the other. Unless you are in a desperate hurry or you have money to burn, you may be better hanging on for one at a reasonable price, rather then going for one at all costs.

Based on past prices, I still believe that around £100 for a fully working machine with power supply is a fair price for both buyer and seller, though, at that price, it is unlikely to be boxed and probably not "pristine". Whilst, as you can probably tell from the rest of the website, I am big fan of the MTX computer, I think that some of the prices are just crazy - don't let me stop you though - in fact, if you want to be the first to break the 4-figure ceiling, I could even let you have one of mine

Memotech MTX 500 32K Vintage Personal Computer

MemotechMTX500 I have had this for a number of years now, sadly most of the time instorage.   I now need to rationalise my vintage computer collection, down to thechosen few!   Here we have my Memotech MTX 500, which comes with the original PSU and somemanuals and litrature.  I have onlytested it with the modulator output on my old portable TV. As it has been stored for so long it has the classic condition of someof the keyboard keys sticking and repeating characters.  Therefore, the keyboard will need a goodcleaning, but as it uses the same key switches as the Acorn Master, which aregood quality units, then it should be perfectly serviceable. It has had a basic power up test and been left on for a while.  The inside is clean and the capacitors lookOk. The stripping on the TV is due to camera synchronisation and not afaulty modulator.

Very Rare Memotech MTX512 Computer / Memotalk Speech Synthesizer

I am selling on behalf of a family member whom was an avid collector of vintage computers. This has been stored in a storage chest within their spare room and has always had the protective cover over the keyboard.

The Memotech MTX512 computer can be seen working as displayed in the images. I would also like to add the computer has been carefully taken apart by a trained IT engineer for photographs and to check the condition, which in his personal opinion is very clean inside and dust free for a computer made in 1983.

Vintage Memotech MTX500 computer

MTX500 in mint condition with packaging (cardboard box has the serial number of the computer on it too)  Damage to top polystyrene, a hole. Demo tape and 2 games (frogger and draughts) Boots to BASIC and has the unique ability to drop into Z80 assembler code, I used this computer at college for my HNC in computers then left it in the loft with its twin for over 30 years. This machine has had little use, but the RF output seems to wander slightly, the trimmer pot needs a minor tweak on the rf output module. This one has two RS232 serial ports out the back, with manual. The other memotech I'm selling does not. Throwing in a period cassette player with it.
