Agreed Paul. I am converting ther BMP files to standard 2 color Black and White
GIF files.

<<I don't really see any advantage in running CP/M on the IIgs (if you
mean CP/M-80 and not e.g. CP/M-86): CP/M can only address 64K RAM
anyway, and the CP/M cards for the Apple II already has that.  Extra
RAM must be put in other memory banks, which can only be used for
e.g. a RAM disk and, in the case of CP/M+, to store major parts of
CP/M itself in, freeing up still a few more KBytes to the
applications.>>

Understood - I just thought having a CP/M emulator to run under any of the IIgs
emulators would be nice to have for use on any of the Mac or PC machines with
such.  But,  it seems that Hank wants to use it with a REAL Apple II machine so
- so much for that idea :)
