Commodore 1551 Disk Drive

Originally known as the SFS481, and designed specifically for the Commodore Plus 4, it is in appearance like a charcoal grey 1541, the drive plugs into the cartridge slot of the machine, using it's own built in interface.

Due to the plus 4 being a poor seller, especially in America, few of these were made, the computer could also take a 1541 or 1571 drive through the serial port, and as they were far cheaper than this drive, this seriously impacted on it's sales, and it was discontinued not long after introduction.

Although the Plus 4 was more commercially successful in Europe, most software was sold on tapes, so the drive did not sell much better there.

 Because it used a parallel port it was enormously faster than the other Commodore drives, The 1551's data transfer speed is about 1 kB per second. It is about 3 faster than 1541.

 The drive itself is single sided 170kb, using 5 1/4 inch media, and used a motorola 6510 processor as a disk controller.

 Our model is fully boxed with poly trays, and in fully working condition.
