I've heard of alledged V20 incompatibilities many times, but never of any report pointing me to a real V20 bug. Of course, the V20 is somewhat faster and can affect timing loops, especially those embodying instructions boosted by the V20. But that's ill behaved programs, not V20. And the problem shows with any CPU at 8 Mhz anyway. The only "real" incompatibility I could ever spot was a program testing if it was running on a 80286 by issuing a PUSHALL isn and testing SP. The V20 is in fact a 80186 and PUSHALL works, but the program crashed on later real 286 instructions. This was zapped away in minutes. Here again, the V20 is not to blame, but the fact it is used in an environment where a 186 is *usually* not expected. The 286 test could have been better. Any other precise information?
