ON DISKETTE
Inserting the Diskette
STEP 1
Turn on your computer, the TV, and the disk
drive.
STEP 2
Insert the diskette with the label side facing

away from you. Be sure not to touch the mag
netic portion of the diskette; hold the diskette
by its protective jacket.

To load the program into memory, type;
LOAD"-",8
The "*" tells the computer to load the first
program it encounters, while the 8 tells the
computer to find the program on the disk
drive—device number 8—instead of on the
Datassette/player—device number 1.
NOTE: If you are loading a machine-language
program, you will have to type a ,1 after the
,8- If this additional parameter is needed, this
will be specified in the program's instructions.
NOTE: Whenever you type instructions, if you
make any mistakes, simply use the INST/DEL
key to backspace and erase, or the
SPACE bar to move forward and erase.
STEP 2
When you are finished typing, press the
RETURN key. The following messages appear
on the screen:
SEARCHING FOR "*"
LOADING
READY.

STEP 2
Place a new, blank diskette in the disk drive.

commands.

ID, type any 2-character identification number
you choose.
