   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 
interpreted to mean "when it was designed" and others took it to mean 
"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 
instruction set.

   (Some people here disagree with this, but their cluelessness is not 
my problem...I've designed with both, and programmed both in assembler, 
so unless they can say the same, they can "talk to the hand", as it
