I don't think it's very hard to make a "minimal" 8008
system, even buffered. I used a 8080, 8224 clock
driver (not hard to find), a 241 and a few 373's for
the address buffering, a 138 to decode memory on 8K
boundaries, a pair of 2114's and a 2716 on my demo
display board. All are available from Jameco. a 7404
and an 00 were the only other TTL on the board. I'ts a
pain to come up with the +12 and -5, but still, not a
big deal.
The "hard" part is finding nice, displayable
components instead of second-source junky plastic
chips.
