computers. However, each computer has different requirements for speed of

incoming data. Therefore, there is a software seitch for selecting which

computer's speed to use. The drive starts out ready for a Commodore 64. To

switch to VIC 20 speed, the foIlowing command must be sent after the drive is

started (power-on or through software):

OPEN 15,8,15, "UI-": CLOSE 15

To return the disk drive to Commodore 64 speed, use this command:

OPEN 15,8, 15, "UI+": CLOSE 15

More about using this type of command is in chapter 4, with a detailed

explanation of the U (user) commands in chapter 7.

3. USING PROGRAMS

LOADINGPREPACKAGED PROGRAMS

For those of you interested in using only prepackaged programs available

on cartridges, cassette, or disk, here's all you have to do:

Using your disk drive, carefully insert the preprogrammed disk so that the

label on the disk is facing up and is closest to you. Look for a little notch on the

disk (it might be covered with a little piece of tape). If you're inserting the disk

properly, the notch will be on the left side. Once the disk is inside, close the

protective gate by pushing in on the lever. Now type LOAD "PROGRAM

NAME", 8 and hit the .~U"IU~~. key. The disk will make noise and your

screen will say:

When the READY comes on and the:~:is on, just type RUN, and your

prepackaged software is ready to use.

LOAD

The BASIC commands used with programs on the disk drive are the same

as the commands used on the Commodore DatassetteTM recorder. There are a

few extra commands available for use with disks, however. First of all, the

program name must be given with each command. On a Datassette, you could

omit the program name in order to just LOAD the firs program there. On disk,

since there are many different programs that are equally accessible, theprogram
