CP/M 3.0 On the Commodore 128
An important part of the opening display is the following two-
character message:
A>
This is the CP/M 3.0 system prompt. The system prompt tells you
that CP/M is ready to read a command entered by you from your
keyboard. The prompt also tells you that drive A is your default drive.
This means that until you tell CP/M to do otherwise, it looks for pro
gram and data files on the disk in drive A. It also tells you that you are
logged in as user 0 (the default user number, indicated by the
absence of any user number).
NOTE: In CP/M a single disk drive is identified as drive A. This is
equivalent to unit number 8, drive 0 in C128 and C64 modes. Usually,
the maximum number of drives in CP/M 3.0 is 16. However, on the
Commodore 128 the number of drives is limited to four physical
drives, identified as A, B, C or D) and one logical or virtual drive, iden
tified as drive E. See page 198 for more information on the virtual
drive E.
If you have the Commodore RAM expansion module, drive M is avail
able as a RAM disk. Refer to your RAM expansion manual for details.
