Hey everyone,
I know it's been a while since I'v posted, but recently I got a rather large load of stuff from an elderly lady down the street (for free). Among a 286, TS1500, various 386s, I got a box with a bunch of old 5.25" floppy drives, and a homebuilt backplane. (I'll get pics later) Inside there were two different sets of slots, 5 S-100 form slots, and 2 44 pin slots (exactly the same as the apple one slot, cards fit in my replica.) 4 of the five cards on the 100 pin bus were intel branded:
1 I/O interface
2 8080 I CPU card
3 4kbyte SRAM card
4 PROM card
All are early 70s, pre 75. I would guess that they were s100, except for two problems:
A. They are taller than and s100 cards i'v ever seen
B. There are no voltage regulators on the cards, the chips *seem* to be getting power directly from the bus.
Do any of you know if these are s100, and what they are worth?
Thanks, Will
