I'm into old stuff and looking for:
Original Science of Cambridge PCB, with or without parts
An 8 inch disk drive
Various somewhat older parts:
- 2111 - RAM (256x4 static RAM like MM2111-1N, NEC D2111, Intel P2111A-4, AMD AM9111BPC)
- DM74S571 (SN74S571N, MH74S571 - of course with no fuses burned yet...
- Crystal 4.433619 MHz, the big model, not the normal HC49 model
- NSA1198 (calculator display) HP 5082-7441, CQYP95, ALS318A
- LM340T-5.0 (not its replacement the 7805)
- DM80L95 (74LS365, 80C95)
- DM7445
- DM7408 (may also be 74LS08)
- 6264 or 62256 RAM
- 2864/28256 (EEPROM)
- DM86S64CAB
- DM74L86 (!! different pinout from 74LS86
- 80L95 (80C95)
- 2N2926G
And eighties speech synthesizers.
