Now that we're on the subject of 6600's and the like... I have a bit
of a puzzle. I have some CDC 7600 modules; these consist of 8 thin
PCB's, with metal shielding in between. On the back, there are 8 rows
of 16 pins, and on the front there are 8 rows of 6 recessed pins,
staggered (I believe for te

I can't speak to Cyber 70 systems, but the 6500 at LCM

In serial numbers 1-7 only nominally -- the clock was a ring oscillator, tuned
by tweaking wire lengths. Starting with serial number 8, there's a c
