There's a datasheet for the V20 (uPD70108) on

has dc/ac characteristics, timing diagrams, pinouts, etc.
Problem #1: PartMiner
seem to have locked access to *ALL* the datasheets.
Fun, fun, fun. What was once a genuinely useful service has now "gone to the
dogs"... Thank-you dot.bomb...
Sorry,
I can't help on the actual hardware manual. Can you get by with
docs for the 8088? I thought it was a drop-in replacement.
I might be able to use
the 8088 docs. The V20 is *supposed* to be a drop-in
replacement, but IIRC it needed some (minor) BIOS alterations to get it to
work properly in PCs when the 8088 was swapped with a V20.
Where did you find the software manual?
www.google.com - I searched for "NEC V20 Hardware Manual".
Later.
