differntly from 8088 which shaved a few cycles of the execution. For the
same clock V series were between 5-10% faster. Also the V20/V30 had 8080
emulation.
I had forgotton about the V20's. Still a good way to get a few more % of
speed.
I don't think anybody used the 8080 emulation unless you had CP/M software
you needed to run. MSDOS was the only big OS being pushed as I think
Pascal and CP/M86 had been discontinued by then.
