Chuck,
Personally I loved the Nec V25 and V35 microcontrollers for small
projects. For a "decent resource" on the Nec V20/30 did you look at
the Nec User's Manual for the V Series (~ 1 thick, Circa 1992)?
I have one around here somewhere.

It's also worthwhile to mention that the
V20/30 has instructions
that none of the Intel x86 members has, such as packed BCD string arithmetic.
I have never found a decent resource on NEC V20 special opcode
programming; the only stuff I've found has been on how to detect an
NEC through bugs, and searching via google has been unproductive for
the last 20 minutes. Is there a resource for what the extended
instructions were, or is that lost to paper history?
