It was a wirewrapped 6502 with rewritten Kim monitor in 4 1702 256x8 eproms. The output routine was sent baudot code. With things like .EQ. for = and .LE. for< etc. Input however was a ASCII keyboard from Jameco. You could get them for around $10. Later I made a tape interface so that I could load tiny basic. I first had only 1k bytes of ram ( 8x 2102) but finally got up to 32 k with 8 4k boards all on 22 pin double readout PCB's hand etched by a friend here in town. Took a lot of power. I still have it in the basement somewhere. A flood ruined my model 15 and my speedgraphic camera. along with a lot of other stuff. Was not exactly a flood, we had a ice storm and loss of power for about a week and the basement filled up with water since the sump pump did not work. My second computer was a Rockwell AIM-65 that I put into an old IBM took kit. MY first lap top. It had a little thermal printer and a LED alph numeric display. I got a 32kB memory board that was intended for, I think, OSI computers. That board cost $600 those days. This was around 1979. I still used my model 15 sometimes for printouts but replaced it with a surplus chain printer, about 250 lb monster. I knew the company I was working for was going bust so I also added A/D and D/A to it with the intent of going into consulting. However, an engineering position opened up at the University of Kentucky in the Physics department. I applied and took my computer in the attache case. It impressed them, but they showed me their fast Z80 s-100 computers and I challenged one professor to a race. We both had Microsoft basic and entered the same program, something like 10000 multiplies, I won. I got the job too. Sorry to be so long winded, but you did ask.

It is down stairs and perhaps may still work if the old eproms are still good.
