CDOS users: Get M7CD-1.ASM, the overlay for Cromemco systems.

After you overlay MDM720.COM using DEBUG, patch the following
locations to NOPs (binary zeros): 2AB7, 2AB8, 2AB9, 2ABA.

This will disable the CP/M disk stat call function 1Fh which is
not implemented in the current version of CDOS.  The MDM720 DIR
function will then work, but will show 0k left on the disk.
That's livable, and certainly better than before when CDOS gave
an error message and jumped out of MDM720 to return to the system.
