I remember upgrading an XT clone with a V20 back in those days and it

I did the same, but to more efficiently run CP/M programs under an emulator
for MS-DOS. With better instruction-set compatibility with older
processors, the V20 had to do less emulation and could run more straight
code.
The target application? Scott Adams adventures for CP/M. :-)
I still have a V20 and a V30 left over from old C= stock from the local
service center that closed 10 years ago.

I'm trying to track down a copy of the NEC V20 Hardware Manual...
Wasn't the V20 100% Bus (and thus hardware) compatible
to the 8088 ?
