I picked up a couple of IBM circuit cards today for ~$1.50.
The first is about 3.5" x 4.5", has 2 24 pin connectors, 5 of the IBM
square metal IC cans and many other components. It has id numbers:
75114 4B01536A1590 VCC
The other is 7" x 4.5", has four 24 pin connectors, 6 larger metal IC
cans , 9 DIP chips and misc components, it is marked
4161595A2828 VCC13607010
Does anyone know what these do and what system they are from and their
approcimate age ?
They came in nifty plastic "conductive containers" marked IBM with small
windows allowing you to see what is inside.
If nothing else they are great examples of IBM technology.
