Commodore Diskdrives

Commdore started to make floppy drives via the IEEE-488 connection. This means the drives had to be quite intelligent and in fact were complete computers (650x cpu based) with their own Disk Operating System. The faster parallel IEEE-488 bus was replaced in the consumer line with a equivalent serial bus called IEC, the result was a compact cable connection and a low transferspeed.

Here are shown the VC1540, 1541, 1541-II, 1571, 1581, a 1541 clone and the CBM3040.
