CP/M - test-drb@ccmp.vtda.org

13 Jun 1998

Did MP/M run on Z-80s? BTW, is there a reasonable chance the CP/M on
one micro w/5.25" disks be compatible with another with 5.25" disks,
i.e. my apple with a C-128? Also, if a computer can run CP/M 3+ can it
run eariler versions? (Note i'm not talking about apps here).
...
 OK to fair. ;)  It was file level password protection
and required the 
whole colume to be enabled for it.  Security level was low though.  If  the 
...
 user could assemble and run a program they could write
code to access  the 
...
 disk directory and toggle the right bits and they had
control.  It was
aimed at captive applications where the user had limited resources and 
could not get directly at the file system.  Many of the things in CPM3 
are there to provice more direct compatability with MP/M.

As to weird, no most of the additions they did were similar to the ZCPR 
groups and other were doing in parallel and had sound basis.
