Kyotronic 85

Untitled Document

Cliff Harris reports:

I bought a Kyotronic 85 new at a computer swap meet at Advanced Computer in Santa Ana. One thing I think was interesting is that the motherboard had a Radio Shack part number on it.

I upgraded the memory to 16K and later tried to upgrade to 32K but Radio Shack had discontinued the memory modules.

As I recall, it had PC board traces for a modem but no components were mounted and there was no provision for the telephone jack in the plastic case. Your technical information section shows "Phone", but I don't believe that's true (based on my memory, which could be wrong).

I wrote a hex/ASCII dumper and disassembler in BASIC and dumped the ROM to a printout. Later I rewrote it in 8085 assembly language, which was about 10 times faster, and POKEd it into memory from BASIC. I translated all the op codes to hex and then to decimal for the POKEs. I did it by hand because I didn't have an assembler.

I gave the computer to a co-worker who wanted a "project" to work on in his spare time, so I don't know what happened to it.
