I've inherited another MTX, this one is a MTX 512 but fitted with a 32K MTX500 mainboard.
I am sure I read somewhere that one of you fine chaps could sell an internal memory expansion card?
Are those still available - can anyone please point me in the right direction in terms of who to contact and price?
Thanks

Re: Memory Expansion
Hi Dave
Thanks. The CFX is 'just' (I say that without meaning any offence!) an interface for Compact Flash program storage? Or does it have memory on board as well?

Re: Memory Expansion
You're right, no memory, it's "just" a disk drive emulator using CF

Amongst all it's other goodies REMEOrizer also comes with Ram

If you have the parts, building a ram expansion's not that hard!
You'd need static ram chip 32,128 or 512k a GAL or similar, some Matrix board and an edge connector. I put this one together for testing CFX
a 20 pin GAL would do for 32k or 128k. In order to make the 512k available on both Basic and CPM I had to use a 24 pin part, the smaller ones just couldn't hold enough permutations
