Maybe one of those 48 bit general purpose I/O cards (sorry Al, I think
they're mostly ISA) is the way to go? Seems like they were reasonably
priced (~$80) and don't require any up-front engineering on our part.

(A long while back Werner and I were thinking about using one of those
in conjunction with one of the CPU emulation cores to make a PC-based
ICE. Probably wouldn't do realtime (ISA I/O is pretty slow) emulation,
but would get pretty close for old 1-4Mhz stuff. Probably be good for
most arcade games as long as the video wasn't generated by the main
CPU...)
