Removing a diskette
Never remove a diskette while the Drive Select light is on, or while a disk file
is Open.
Press the Drive Release Bar.The door will open and the diskette will be partly
ejected. Carefully remove it, taking care that the shiny diskette surface
doesn't touch the chassis or drive door on the way out.
Note: Once a diskette has been seated in the drive, you must shut the drive
door before you can remove the diskette.

Loading the Operating System
When the Computer promptsyou to INSERT DISKETIE, carefully insert the
Operating System diskette into the drive.
As soon as you close the drive door, the Computer will begin the Operating
System bootstrap.
(If nothing happens when you close the drive door, the diskette is probably
inserted incorrectly. Remove it and re-insert it correctly.)
The Computer will then execute a dignostic program before starting the
Operating System. This lets you verify that the entire system is in working
order - before you attempt any data processing.
After Completing the Diagnostic Program, the Computer will load the
Operating System. See the Operating System Manual for details.
