On a vaguely related note, I found it amusing that
there was a well known
hack for Cray's (or perhaps 6600's) which were misbehaving: put a
Tektronix scope probe on a test point that generally had one there during
final system checkout. The load (extremely mnimal by design) was just
enough to stabilize the system.
There was also the story about the major difference between a Cyber 72 and a
Cyber 73 was just a timing capacitor... Very expensive capacitor :-)
