I have found a bunch of very pretty HP cards that I would like to ID.
They are about 12 inches long and 4 inches high with edge connectors just
off the middle with 22 connectors per side. Most have these on top and
bottom.
All have 02640 in the numbers somewhere.
Examples of the full numbering are:
HP 42L 02640-60256 A-212-42 8080 Processor 665494. 42-2230 4242-3896 97
of 175 (Has no 8080, only an 8048)
HP 42F 02640-60065 E-1914-42 665983 Memory 4K. 42-2230 4241-7975 119
of 250 (Has 8 X National Semiconductor MM5280J memory chips)
When I say pretty, I mean lots of gold circuits very aesthetically laid out.
