MAKING DISK BACKUP COPIES
To make a backup copy of a program on a disk
you will initialize (or format)a blank disk, a pro
cedure we will explain in the steps that follow.
Then you will have to load the program into the
computer from the original disk and unload the
program onto the newly initialized disk. Using
one disk drive, this process takes several passes.
Here's how you initialize the blank disk:
STEP1
Turn on the disk drive system, the TV set, and
the computer console.
STEP 2
Open the little door on the disk drive. Pick up a
blank disk and hold it with the label facing up
and the part with the uncovered section of the
disk facing away from you. Insert the disk into
the disk drive, and close the little door.
STEP 3
Plug the Disk Manager Command Module (the
cartridge that came with your Tl Disk Memory
System) into the cartridge slot on the computer
console.
STEP 4
Press any key on the keyboard.
STEPS
Press the 3 key, to select the Disk Manager Com
mand Module.
