Yes it would muck up the works. The part was uPD7220. I have a few
and likely apnotes and all as well.

Make sure you google for uPD7220 (that's the
NEC prefix)

That was my mistake -- I kept searching for NEC 7220 and NEC D7220,
without the 'uC'. Couldn't find anything. I have a copy of it now, thanks!

Note that the Intel 7220 (usually D7220 or P7220) is completely
incompatible, as it is a bubble memory controller for the Intel
1 Mbit bubble memory parts.
Someone else already pointed out that the Intel's equivalent
of the NEC uPD7220 was the Intel 82720.
