Re: University credentials used by third parties

Here is one for those of us who remember wire wrapped boards - It was often
the case that the messier the wire runs, the better the results, because
long parallel runs would create cross-talk.  I once wire wrapped a test
board to test small cards that augmented a PDP-8s' capabilities to do math
and other functions and it worked great.  Then it got sent to get built for
deployment and we got one that was really neat, with wires tied together in
nice little bundles, but the cross talk was so bad that it never worked.
So, we went back to my original prototype, even though it looked like a
bird's nest in there - It validated in my mind why I preferred a messy room
during my college days!

No wire-in-core in my history, but I do recall the baffled looks on CS grad
students in 1989 when I scrapped a long-dead PDP-8 (I think) and showed off
the wire-wrap motherboard.

Here, you mean where you could actually see the wires wrapped around the
core with the sense, and x, y  wires going thru them.

Connecting to different systems meant throwing big two or three position
switches to change which system talked to other systems.
 Plugging in the bootstrap program either push buttoned lighted indicators
or toggle switches on the front of the data general nova or eclipse
computers.
