One other thing.. CPUs..
I've only mentioned Z80s.
Others from the junkbox would be:
8080 (for the three voltage masochist).
8085 (Also makes for simple systems)
NSC800 run it if you got one.
Z180
Z280
ez80 (in Z80 mode)
8085s are common and makes a fair CP/M system. One caveat is that some
(far from all) applicaions software expects a Z80 though, most run on 8080
and above.
