I'm trying to dig up the Chuck Peddle interview where he talks about targeting the embedded 4004 and friends market, I'll post it when I finally find it. The interview mentions achieving functional parity with the MCS-4 chip family as the reason for e.g. the 6530 RRIOT. The 4004 was old by then, but not obsolete. It and the 4040 were still being integrated into embedded systems where cost was a major factor through the late 70s.
