I'm getting this opinion straight from Ted Hoff himself. I don't know
where my notes are on this and I can't remember the details, but I think
there are some significant differences between the 4040 and 4004. The
8008 was supposed to have been based on the 4004 architecture, extending
it with more instructions and such. The 4040 was, I think, a whole
different design by a different team inside Intel.

I'll have to find my notes I guess.
