USING WITH A VIC 20 OR COMMODORE 64
The 1541 Disk Drive can work with either the VIC 20 or Commodore 64 com
puters. However, each computer has different requirements for speed of incoming
data. Therefore, there is a software switch for selecting which computer's speed to use.
The drive starts out ready for a Commodore 64. To switch to VIC 20 speed, the follow
ing comand 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, "U1+": CLOSE 15
More about using this type of command is in chapter 4, wiih a detailed explana
tion of the U (user) commands in chapter 8.
