Jeff Duntemann's Technology Projects 
1978: Cosmo Klein, a COSMAC-controlled robot with radio control and a fully functional arm with gripper. Cosmo and I appeared on TV, in Look Magazine, and in numerous newspapers from the late 70s to the early 80s.

10/77: Cosmo's face was animated using a COSMAC VIP single-board computer from RCA that had an innovative low-res graphics system for TV display.

1978: The RCA COSMAC VIP had a nice system for loading and saving software on cassette. I wrote a simple paint program in 256 bytes (!!) of machine code, and with it drew all the animation bitmaps.

1978: Because much software written for the COSMAC ELF made use of ELF-specific I/O, I wire-wrapped an adapter for one of the VIP's two board slots, providing ELF-compatible I/O to the VIP. This included eight toggle switches, a push button, four TIL-311 hex digits for address display, and two TIL-311 hex digits for data. I wrote it up as an article for the 10/79 Creative Computing.

1978: I bought a Heathkit paper tape reader/punch kit, and interfaced it to the COSMAC system. The reader worked beautifully, but the punch was terrible. The hole spacing was so bad it couldn't even read its own tapes, and I sold it soon after. Punching the tapes was always a problem, as I never found an ASR 33 with a punch at a reasonable price.

1978: I bought a nice little Logan change-gear lathe in 1976, but it stayed in Carol's folks' basement until we bought our own house in 1978. Using the lathe I was able to make parts for both my telescopes and my robot, Cosmo.

1978: I did a huge amount of work on my basement shop at our first house on Campbell in Chicago, only to be transferred to Rochester NY nine months later.
