Welcome to the world of massive storage of information. To use your 1001 disk drive with the Commodore 64 you will need an IEEE interface and a F-I cable. With a 8-128, 8032, or Pet computer you will only need a P-I cable. When using the 1001 disk drive with another disk drive, you will have to change the device number of one of the drives (All Commodore disk: units come from the factory with a device number of 8). Read the following section how change the device number, if you have more than one drive. The 1001 disk; drive has the same disk storage format as the 8250 disk drive.
The device number can be changed temporarily changed via a software command or program. The device number may be permanently by modifications within the disk unit.
