Computers and other hardware containing the 8008 microprocessor - test-drb@ccmp.vtda.org

What you've said here is probably the case.  THIS environment is the only
one in which I've ever encountered the claim that the 4004 was in any way
related to the 8008, eexcept for the label.  Nevertheless, since I didn't
know much about it then, I probably know even less now.

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.
