Re: Hello from a new member

John, I don't know whether a memory board made any difference to the links on the main board. I can check though, my original "MTX512" also had only 32k on the main board, with the extra 32k on a RAM card. I will have a look later. Given what you said about the RS232 plastics though, it may be that ...

Re: Design your own 20MHz Z80 microsystem.. MTX PLUS !!

Hi John, The original idea that Lez had for a group of Memotech enthusiasts developing Z80 systems did stall. I think I was the only person on here that was interested in doing it, most folks here are pretty much software orientated. There is a similar thread on a Tatung Einstein forum which did see...

Claus, the board is at risk of losing any value if the ever increasing amount of SPAM is allowed to continue.

Re: Hello from a new member

Oh well, never mind. As you say, beautiful machines. There are a couple of options to upgrade the RAM, as it is highly unlikely you'll find a Memotech 32K expansion, there's my sorry tale of woe when I tried it here http://primrosebank.net/computers/mtx/projects/ramupgrade/ramupgrade.htm If you don'...
