Commodore 1541-II Disk Drive

The Commodore 1541-II has an external power supply, one diskette station with one read / write head and a motherboard. On the motherboard you will find RAM and ROM memory, twice a MOS 6522 VIA and a MOS 6502 processor.
The 1541-II is the successor of the 1541 and was introduced to operate along the the C64C.

Like all Commodore disk drives, these drives were “smart” devices. They had their own processor, their own memory, and their own disk operating system.  Basically, a Commodore computer and its disk drive resemble a network!
