    Yes, it is quite rare. Unfortunately, the resolution of the keyboard mystery is rather benign - a user on the zx80zx81 forum has just unraveled it this morning:

  2. Ultra Rare Timex Sinclair 1000 (ZX-81) with BLACK Keyboard?

    I have picked this up for 40 $ on eBay ("untested" of course - I knew I would have to work on it...). This time I also had to replace 2 keyboard matrix diodes (first time I had to do this). The usual...

    Yes, I could do that and put one into Talker/80, but I am already certain that it will fail. I did read out the programmed GAL into a file, compared it to the original, and it was all garbage.

    Uhh, bummer! Understandable that you are getting rid of them.

    I am still using WinCUPL for the old GALs - I don't think they will try to get cash for a 20 year old program :cool:
    At least that's...

    We DIY hardware hackers love the old GALs - Talker/80 uses 2 of them for address decoding and databus latch / tristate buffer.

    Now, to all DIY Talker/80 builders - beware of FAKE COUNTERFEIT GALS...

    And for those who do not wish to assemble it themselves - there are currently assembled ones available on eBay (both M1 and MIII/4 models).

    That's a really neat looking set of clothes, Cary and son! Very nice, great work! The silver color matches perfectly with the Model 1 I suppose - would be nice to see a picture of it with the Model 1...
  12. Interesting build - RPi in a Model III with original keyboard and screen working!

    That must have been quite an effort to put together - too bad it is only a lookalike emulator by now. I wish the seller had saved and repaired the original hardware:

    It seems you have the Hi-Tech keyboard, not the Alps one. They keyboards are old now, so the dust inside makes the bouncing worse and worse. Cleaning can help. But in my case, I could only get the...

    Are you sure that your TFT / TV / Monitor is up to processing the slightly "off-standard" video output that the Model 1 produces? Maybe nothing is wrong with it at all... if possible, I'd try...
