According to a file included with the CP/M emulator, it does appear to be in
the public domain, placed there by none other than Atari Corp. (who also 
appears to be the one who commissioned the port to the ST.) I got it off of
Terminator, though I'll be happy to mail it to you if you wish. Please respond
by email and I'll do it (its over 200K uuencoded/arc'ed so I don't want to be
one of ten doing it :-) )

I'm glad you asked about it though, since I use it occasionally, and find that
a few pieces of functionality and information are missing and was thinking of
bringing up the topic myself. First of all, I can't find any information about
hard-disk support under CP/M, though the TOS filesystem commands can access the
hard disk. Also, there's not enough info to make changes to CP/M itself like
upgrading to ZCPR. (For those of you not familiar with it, the Atari ST CP/M 
emulator emulates a "documented" Z80, i.e. doesn't implement the undocumented
Z80 opcodes.) If anyone can help, please post or email.
