in my mailbox (I subscribed to the Electronic Edition - worked out far
cheaper than the dead-tree version).
Nice to see that someone's built a CDP1861 clone, too - I've only got the
one, and that's half the reason I rarely power up my Elf. At the moment I
need to get a few spare parts in. I've got a few TIL311s, I might have a
CDP1802 somewhere, 40xx logic is easy enough to obtain, but 1861s are like
hen's teeth around here. Natch.
