Well . . . one version of the story, according to Adam
Osborne, in his book
(3-volume set) on microcomputers, was that Datapoint paid for the
development of the 8008 for use in this jewel, then concluded that it wasn't
fast enough, so now Intel had a paid-for 8-bit version of their 4004, which
Osborned didn't say was what this was, but one might see a connection,
nonetheless.
Hi
From what I remember, the 8008 and the 4004 were two separate
projects, developed some in parallel by two separate teams
that didn't communicate much. The way the 8008 and the 4004
treat memory is quite different. The ALU is quite different.
I would say that the 8008 was not just a simple expansion
of the 4004. Because of the overlap in time, I don't even
think that any of the concepts, good or bad, of the 4004
were carried over to the 8008. The 4040 was definitely
an enhancement of the basic 4004.
