IIRC, the V33/V33A was packaged in PLCC or PGA; I believe (without
going digging after my V-series documentation) that the data bus and
address busses are kept separate instead of being multiplexed (as on
the 8088).
In the pantheon of x86 CPUs, it's pretty hard to find a sample of one
of these. I think NEC used it on a model of the 9801, but I don't
think it was deployed very widely otherwise.
Mind you, this is without consulting my databooks; so my memory is a
little hazy. I think if the V33A were pin-compatible with the 8088,
it would have been an instant hit in the PeeCee world.
