Preliminary, my photos from the Vintage Computing Festival - East in April 2022, from the VCF MidAtlantic facilities at
InfoAge in Wall, New Jersey USA. I do not have photos of every exhibit. Here's the VCF-Mid's description of exhibits, workshops, sellers. (c) 2022 Herb Johnson all content execept content produced and owned by others. More as
I find time to add. Last update May 4 2022. - Herb Johnson

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
