Jon "Glitch" Chapman, and IMSAI [vcfe_2022]

I spent time in Jon Chapman's VCF-East workshop, mostly observing. I enjoyed seeing the IMSAIs under repair. And it was good to see people learning to build kits from components, the other activity there that Jon Chapman usually performs during VCF-East. This year, he could not get parts for his kits.

There were a number of people in the workshop, exercising their collective knowledge of these early vintage computers. It was good to see them again, after two years of Covid kept me from VCF-East. Also note: there was a nice exhibit among the other exhibits, of early S-100 computers thanks to Mike Loewen.

Jon and I tag-teamed on one IMSAI fix. He was looking up details on a front-panel signal that wasn't pulsing; but could not find an early IMSAI schematic. While he was looking, I reverse-engineered the circuit to trace it backwards. He found the problem from the schematic, just as I traced it back, to the same one-shot 74121. Replacing it solved the problem; apparently 40-year-old monostables tend to fail, Jon said at the time. - Herb

InfoAge activities during VCF-East

InfoAge lecture, "where on the Moon?" [vcfe_2022] Frank O'Brian gives a monthly lecture on space exploration history at InfoAge. This month was a review of the five lunar sites visited by Apollo astronauts. The lectures are given at the TIROS and Project Diana radio-dish station near InfoAge, a 60-foot dish restored by Princeton University and in use for student research. Check the InfoAge Space Exporation Center Web site.
