What specific model of 1802 is in there? What manufacturer? (CDP1802BCEs
are somewhat common for processors of modern manufacture; I have one
old 1802D that someone paid a lot of money for at one point (ISTR you
can push an 1802D to +10VDC and overclock it, compared to the cheaper
models).
Do you know about the 1802 Yahoo! Group?

As soon as I can find some black paint, I'll be taking pictures of the
Popular-Electronics Elf I just put together a few days ago.

68008s are useful to Sinclair owners. It's not tough to build a homebrew
project with one. We had a prototype async<->bisync adapter based on them
(since our codebase was for the 68000) that never left the lab. If we'd
designed it later, I'd probably have recommended a 68330-type embedded
communications controller.
Good score.
