i guess i was not totally clear.  the driver for the DOS machine can't 
read the Mac _file system_ and, the Mac init cannot read the DOS file 
system.  

the CD-ROM file system, however is a standard, something like ISO-9600 or 
something like that.  thus, mac's and DOS machines can (sort of) 
interoperate with these, as long as the files are in a format recognized 
by both.

obviously, a DOS executable on a CD-ROM will not work on a Mac and 
vice-versa...

i don't know how executor reads the floppy drive directly, but they must 
do something, esp under linux, since i can't even mount a Mac floppy.
