Rana Systems’ Enhancements for Apple’s Apple II 

DOS 3.3 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 addressing any 

combination of Apple Disk II and Rana Elite 

Series Drives. The PROFILE program sets up DOS 

(Disk Operating System) to recognize which  

drives are Rana Elite Drives and which are Apple 

Disk LI drives. The seek rate can also be 

increased by the PROFILE program to take advant-

age of the increased speed of Rana drives.

The enhancements made by the ENHANCE utility  

only apply to a master DOS diskette. Non-master 

diskettes (slave diskettes) are what are created 

when the DOS “INIT” command is used to initial-

ize a new diskette. The copy of DOS which is 

placed on such a diskette is not ENHANCE-able. 

Even though a diskette may say it is a master” 

when it is booted, it may not actually be one. 

The program which says the diskette is a master 

is completely independent of the DOS itself, and 

can be copied br saved (by an “INIT’ command,  

for instance) onto a slave DOS diskette.

Those DOS 3.3 diskettes supplied directly from 

Apple are all master DOS diskettes. In addi- 

tion, any diskette which is a copy of an Apple 

DOS 3.3 distribution diskette, made using the 

Apple COPY or COPYA utility will also be a  

system master diskette. These instructions will 

assume you are using your original DOS 3.3 dis-

tribution diskette from Apple; but if you’ve
