MEMOrizer for Memotech MTX
Andy Key:
http://www.nyangau.org/memorizer/memorizer.htm
are my thoughts on perhaps the simplest way to add random access storage to Memotech MTX machines.
Don't know if I'll actually build it, but an interesting learning experience for me anyway.

Panther:
Now that looks like a Phu project to me to add to the already extensive list ;)
Phu:
I'd be interested in building these (I'd handle getting the boards made, ordering parts and soldering them up) if you decided to go ahead with the project.
I can also do the PAL/EPROM programming.

Andy Key:
This is on hold at the moment.
I'm going to work on REMEMOTECH first.
I've also been thinking it might be better/cheaper to go for an SD Card plus 16KB
ROM, plus SRAM based design instead (a bit like the SDX).
But then again, by the time you've invested the time and effort on that, you could have a REMEMOTECH, which is miles better.
Also, there doesn't seem to be a critical mass of interest, to justify a board run.
Plenty of time to think this through.

Andy Key:
REMEMOTECH is done.
Abandoning the original MEMOrizer design.
Have a new REMEMORizer design, which will be better and will exploit technology developed for REMEMOTECH.

I am hoping that a REMEMOrizer can be made for < £100, and that folks might view this as a reasonable price for "disk" and "virtual tape" support, allowing loading and saving in seconds.
Like with REMEMOTECH, I plan to make all the documentation, VHDL and driver source available so anyone that is interested can make their own.
I've been sent lots of old-school electronics components and tools, including PALs, GALs, DRAMs, SRAMs, EPROMs, copper boards, GAL+EPROM programmers, ferric chloride.
So in principle I could do this the old-school way.
However, my soldering is very poor, so you will see the design takes a more modern approach.
