Commodore 1541

The Commodore 1541 is best know [floppy disk drive]? for the Commodore 64. The 1541 was a single sided 160 kilobyte drive for 5.25 disks. Converting to "flippy disks" (disks that could be turned over) would give another 160 Kb.

The disk drive used [Group Code Recording]? and contained a [6502 processor]? as a [disk controller]?. Some people wrote code for it to vibrate the head at different frequencies to play tunes.

The transfer rate was about 300 bytes per second. The 1541 used a bit-serial version of the [IEEE 488]? parallel protocol. Some third-party speed-ups could transfer about 4 kilobytes per second over the interface, and some "fast loaders" managed up to 10 kbps.

The [Commodore 1570]? was an upgraded 1541 for use with the [Commodore 128]?.
