I was sort of lucky, by 1978 / 1979 I was playing moonlanding game on a
Commodore PET 2001?.. at work.

There also was the 'motorola max board' some guys were having fun with.

I myself designed and build a video digitizer that year, using TTL logic.
A whole board full, only to have somebody comment: 'I just did see that in
single chip for sale'.
Well the learning experience was worth it.
Do remember the group made a video link at what was it 10 GHz? with a Gunn
diode in a cavity,
FM modulated.

Did some demodulator filter work on that.
Very interesting work place.
