July 2017

  • I have just completed a quite interesting repair on the MTX500 given to me by Wolfgang Joerger. As well as the almost obligatory VRAM fault, the machine had a failed TMS-4764 Mask ROM - direct replacements for these devices are not available - read how I resolved the issue here.

  • Posted a copy of the original CP/M ROM from the FDX SM1 Interface board
  • Another generous donation from a, or should I say an "ex", Memotech owner from Germany!

    • It is in great condition and early indications are that it is fully functional - more details soon
  • Bill Brendling has reverse engineered the FDX CP/M 80 Column card driver - full details here

December 2016

  • MTXPlus+ development continues :-
    • I am currently working on resolving a CPU CPLD timing problem
    • Tony is working on modifying the video board firmware to handle Andy's HEX-TRAIN
    • The Eurocard prototype boards that I used are hard to find - so I have designed a replacement
  • Used some of the time over the holidays to fix the "colour" problem on one of my FDX 80 Column boards
  • Martin has released a small firmware upgrade for CFX, incorporating additional commands from MTXPlus+

 

November 2016

  • Memofest 2016 was held at my place on 29/30th October
    • Notable highlights included :-
    • Phew! - now that is over, I can get on with MTXPlus+ etc. (I hope!)
    • The MTXPlus+ CPU PCB is back from manufacture, with just one minor error this time!
      • Testing was a nightmare, the board appeared to be u/s but it was actually a PLCC socket fault
      • (Martin was able to test the board and firmware on his system to confirm that it was not faulty)
      • Next up - the I/O board . . . . . . . .

 

October 2016

  • I am just back from holiday - but things are coming along nicely for Memofest 2016

 

September 2016

  • Gilles Bronchain has kindly sent me some photos of a pair of MTX512s with consecutive serial numbers that he obtained from Memotech's French distributor. The machines have what appears to be a locally developed video convertor to generate a SCART output from the MTX Video board.
