There is a product called "The Bridge" (sorry, forgot the name of the
supplier) that has a CP/M emulation system.  There were two flavours:
8080/Z80 software emulation, and full hardware support (4 Z80's sitting
on a "peripheral CPU" card).  The latter was pretty fast.  I think that
they had higher speed bitslice Z80 emulator cards in the works.  Then again,
the hardware was unibus (for a VAX).  I saw it running wordstar and
a few other things under VAX 4.1 BSD.  We were going to get them to port
it to a Z8000 UNIX box until our project folded.
