It was thus said that the Great Noel Chiappa via cctalk once stated: > > "The [8008] was commissioned by Computer Terminal Corporation (CTC) to > implement an instruction set of their design for their Datapoint 2200 > programmable terminal. As the chip was delayed and did not meet CTC's > performance goals, the 2200 ended up using CTC's own TTL-based CPU instead." > > The 8008 was started before the 4004, but wound up coming out after it. (See > Lamont Wood, "Datapoint", pg. 73.) This is confirmed by its original name, > 1201 - the 4004 was going to be named the 1202, until Faggin convinced > Intel to name it the 4004.
I found this Youtube video https://www.youtube.com/watch?v=g9_FYRAfyqQ about the register set of the 4004, 8008, 8080, Z80, 8086 (and so on) to be interesting. I don't think it's 100% accurate, but it gives (in my opinion) a decent overview of the history of the x86 register set. -spc
