From The Free On-line Dictionary of Computing (30 December 2018) :
(C64) An 8-bit Commodore Business Machines
personal computer released around September 1981.
Prototypes were (apparently) made before Christmas 1980 (and
shown at some computer fair).
The CPU was a 6510 from MOS Technology (who were a
wholly owned subsiduary of Commodore at this time(?)). The
C64 had 64 kilobytes of RAM as standard and a 40-column
text, 320x200 pixel display generating composite video,
usually connected to a television.
DMA-based memory expanders for the C64 (and C128) allowed
128, 256, and 512 kb of RAM. Several third party
manufacturers produce accelerators and RAM expanders for the
C64 and C128. (Some, risking a holy war, compare this to
putting a brick on roller-skates). Such accelerators come in
speeds up to 20MHz (20 times the original) and RAM expanders
The C64's 1541 5.25 floppy disk drive had a 6502
processor as a disk controller.
