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-
dressing any combination of Apple Disk II and
Rana Elite Series Drives. The PROFILE program
sets up the CP/M operating system to recognize
which drives are Rana Elite Drives and which are
Apple Disk If drives. The seek rate may also be
increased by the PROFILE program to take advan-
tage of the increased speed of Rana drives. If
the disk is run on another Apple the enhanced
CP/M will automatically recognize which control-
lers are Rana and which are Disk If and only try
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
only to temporarily make a Rana drive act like
an Apple Disk If drive and confine the files to
the first 35 tracks of the disk This feature
is useful for creating a disk to send to other
Apple CP/M Users.
As you have probably noted by now, these in-
structions keep referring to Microsoft’s Apple
][ CP/M 56K version. The Elite Enhancements for
CP/M only apply to the 56K version Rana does
not support enhancements to the 44K version of
CP/M since doing so would require "stealing"
space from the user’s program area in memory.
Something which Rana absolutely does not want to
