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.
The 4004 was first in production and it would be many months before the
8008 was built. The two were related in that 4004 was launching
technology and really based on the calculator styled ALUs the 8008 was
remarkably similar in that is was still a single accumulator machine
and used a data ponter register (HL) as a ram pointer. There are other
similarities between them and they relied on CPU technology that was
before them though no micro processor.
