Memotech 16K RAM pack - working. £20 plus p&p
For sale is a working 16K Memotech RAM pack. £20 plus p&p (UK preferred due to the hassle of selling abroad now). This has been tested loading various 16K games, power cycled numerous times and left soak testing playing The Gauntlet to itself for a full morning. I have refurbished the case end screw...

Memotech 16K RAM pack - broken connector. ZXPand case? £10 plus p&p
I have a Memotech 16K RAM pack up for sale. As you can see the connector is somewhat broken! £10 plus p&p (UK preferred due to the hassle of selling abroad now). It may be that this works if you replace the connector but I have no idea. I suspect it is best used as an original ZXPand case or a repla...

Filesixty keyboard £15 plus p&p
I have a FileSixty keyboard for sale for £15 plus p&p (UK preferable due to the pain that it now is sending stuff abroad). I have given this a gentle wipe over and pressed all of the keys on a zeddy and all worked. Not sure what glue you need to use to stick this on! If interested please post on her...

Re: Zeddy displaying wrong characters on screen
A cell from a de-capped 2c184 ULA, the second picture is a cell with the overlay from Sinclair. I've had one or two that partially failed, membrane keyboard presses causing a crash but with a Memotech plugged in all ok. Replacement of the ULA cured it so not a board fault. Great photos! I have ‘The...

Re: Zeddy displaying wrong characters on screen
The ULA is, if I understand correctly, basically a collection of logic gates in one chip, so it's possible for it to partially fail without completely breaking down... if that makes sense. That does make sense - I have some ‘danger ULAs’ that are part failed that I keep for test purposes. It doesn’...

Re: Zeddy displaying wrong characters on screen
I put a different ULA in and it works perfectly. Put the old one in and back to Venusian.
Any ideas how a ULA could do this? Given that it pretty much works fine when a RAM pack / Spand is plugged in?
