3. ENHANCING APPLE‘S APPLE II DOS 3.3

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 advantage 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 initialize 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 distribution diskette from Apple; but if you’ve
