This CP/M Emulator is one of the best that I've ever seen for any
platform. It can mount folders as disks just by entering the mount
point at the command prompt (b: for example) at which point it will
automatically trap the request and open a friendly dialogue box for
the required folder to be selected from. It comes with tools to
convert CP/M files into files that the Mac can use. In fact, about the
only thing that it doesn't do is support CP/M GSX graphics extensions
- but that isn't too much of a hardship since most CP/M computers
didn't support them either.
