Me, if my "Build a 6502 computer" project flops. At the moment, I need
veroboard, DIN41612 connectors and turned-pin IC sockets.

6502: Still manufactured by The Western Design Center:

Z80: The CPU that refuses to die (!) - Zilog still make it IIRC:

CDP1802: Do Intersil still make 1802s? IMHO the architecture is "a bit"
quirky. Then again, I learned assembler on a 6502.

What sort of UART? 16450? 16550?
I'd be very tempted to add GPIB (aka HPIB, aka IEEE488) just because it's a
very usable bus for connecting stuff like disc drives up.

I'd also add an IDE interface and an 80MB hard drive - fun factor again :)
Later.
