Install the diskette into DRIVE 0 (left drive) so that the write protect
notch is at the bottom. Be sure to close the door on the drive.
( )
Type in the minifloppy disk boot character on your terminal. Check your
computer's monitor documentation for the correct character. If the disk unit
does not respond, recheck each step of this instruction set then refer to the
IN CASE OF PROBLEMS section - of this manual.
Using the Disk Unit
The minifloppy disk unit is designed to be as straightforward and easy to use
as possible. There are certain things that the user must be aware of, however, for
correct operation.
All memory in the computer must be operational for the disk to operate
properly. If any doubt exists, run the memory diagnostics to verify correct
operation.
Diskettes should always be inserted with We WRITE PROTECT notch nearest the
LED'S on the drive and with the label outward. Having this notch closed with a
piece of tape will prevent the disk from being written upon. Leaving the notch open
will allow write privileges.
The LED indicators on the front of the drives are drive select lights and are
activated only when the particular drive is selected. They are not power
indicators.
The disk controller has been designed to select the drive and turn on the
drive motors only when necessary. When the computer requests data from the disk,
the motors will activate and the correct drive will select. After the information
has been retrieved the drive will deselect, and after approximately one minute the
motors will turn off.
NOTE: Some versions of the disk operating system will keep a drive selected
after an operation is finished. This is a normal condition.
Just like cassette tapes, diskettes are made of magnetic materials and can be
era by stray magnetic fields. Also, it is an excellent idea to back up all
important disks on a spare diskette. The following precautions should be followed
concerning diskettes:
1.
Return the diskette to its storage envelope whenever it is removed from a
drive.
2.
Keep diskettes away from magnetic fields and from ferromagnetic materials
which might become magnetized. Strong magnetic fields can distort recorded
data on the disk.
3.
Replace storage envelopes when they become worn, cracked or distorted.
Envelopes are designed to protect the disk.
