Subject: UniDos Coprocessor

The UniDos Z80 coprocessor card is made by MicroSolutions, producer of
the Uniform software product for handling foreign-format diskettes.  I
have their card and am extremely pleased with it.  It seems to run all
standard CP/M programs that I have thrown at it without problem and much
faster than on any of my real CP/M machines.  So far, however, I have
not been able to get Z-System running on it.  Even if the code would
run, of course, there would be problems because of the fundamental
differences in MS-DOS file structures (CP/M user numbers vs. DOS
subdirectories).
 
I also cannot tell you much about how it works.  All I know is that
while emulation is turned on, I can still do all of my DOS work just as
before.  They have a very good system for handling both DOS and CP/M
applications transparently.
