I have received some follow-up correspondence to my posting in comp.arch about the V80, which I summarize below. > And the question foremost in everyone's mind... is it an 80386 clone? > -- Chuq Von Rospach, chuq@Apple.COM No! Not at all! It is NEC's own architecture. In native mode, the V60/70/80 carry none of the bagage from the old 8088/86. The architecture is roughly similar to that of a VAX. The only similarity to the 8086 architecture is in emulation mode (where the V60/70/80 execute 8086 object code). Also, in contrast to the 80X86's, entering and leaving emulation mode is painless. > I hope the V60 is popular in Japan, because it doesn't look like > anybody uses it in this country. . . . > Too bad, the V60 was a delightful chip to program.
