MOS 6502


MOS 6502 4084	HONG KONG HH324552 2

This CPU is built in my Commodore CBM 1541 disk drive for the C64. The 1541 has its own CPU, used as a controller. This made this drive comparably fast and opened posibilities for even more speed enhancements from third party manufacturers. Some specific programs for the C64 even used the floppy CPU as a co-processor :-)
