Well, I had a small PDP-11 machine (a DEC Pro-350) that was nice, but it was built as a GUI desktop, and as such it pales by comparison with anything as recent as an 80386-based system. Any geek points it was worth were quickly lost when it wouldn't boot and/or made a terrific racket when it started up...

I'd like a small machine with toggle switches and LED displays (either seven segment or discrete LEDs, a la PCs of the '70s), even an 1802-based system, as long as it also had a serial interface with some sort of useful monitor/assembler... I suppose I could make something from a microcontroller, but I'd rather have a classic CPU (6502, 8080, Z80 or even a PDP-11). The Apple I replica is nice (I have one, but I never put it in a case - I really should, it was a lot of soldering! ;^) but I want to futz with toggles...
