ELITE SERIES USER MANUAL CP/M ENHANCEMENTS
4.ENHANCING MICROSOFT APPLE II CP/M 2.2
Rana Systems Enhancements for Microsoft’s Apple
if 56K CP/M 2.2 allow automatic accessing of 4
drives from the Rana Elite Controller Card and
the additional capacity of the Elite Disk
Drives. The Controller Card is capable of ad-

CP/M will automatically recognize which control-

to access the correct number of drives for the
particular controller type. Changes in drive
combinations may require redefining.
Drives may be temporarily reconfigured in memory

is useful for creating a disk to send to other
Apple CP/M Users.

CP/M since doing so would require "stealing"
space from the user’s program area in memory.
