I appreciate your expertise. Will be looking into the upgrade kit.

Disassembling my Z-120 today, I saw it has a 85-2653-1 5Mhz model main board. From what I understand, this should have 192K total in the three memory banks. I know a later 8Mhz board model had 768K on it. These are TMS4164-20NLJ chip, which are listed as 64kbit / 8KB chips if I read things...

I am intensely interested in seeing how that reproduction project goes. I have a Z-120 that is itching for one of those cards. And yes - at this juncture, I would not be surprised that you have the only functional original left on the planet.

Yes, I am aware of that incredible board. One of the members of this forum has been working on reproducing a clone of it. Would love to have one.

Does anyone know what the last/latest commercially produced S-100 bus computer system was? I would assume it would have been around 84 or 85 at the latest as ISA bus computers took over. But I am curious what the absolute final form, most advanced refined form of an S-100 computer turned out to...

Excellent update! Please let me/us know if the board works as intended. I've got a Z120 all in one that I would love to bring closer to the PC MS-DOS world. Is there a potential for more of those replicas to be produced for the few of us left in the world who could put it to use?

Rich did you ever get what you needed on this project? Very interested in your progress on that project.
