Ok, maybe I'm being impatient here. I do have a headache.
I'm quite [painfully] aware of the fact that the 8086 was the chip
the 8088 was a scaled-down version of. The 8086 was introduced in 1978
and the 8088 was introduced in 1979.
But we were talking about the IBM PC, which was based on the 8088.
We were talking about when the machine "came out", which some of us

"when it first shipped". We were talking about the PC architecture,
If you want to talk exclusively about the x86 architecture, though,
that actually dates back to 1974, to the 8080. The 8086 is largely a
16-bit extension of the basic 8080 architecture, implementing
substantially the same internal structure, register set, and
