The Commodore 64 is the best-selling single
personal computer model of all time. A pre-production Commodore 64 was first introduced at the winter
Consumer Electronics Show in January 1982 by the manufacturer,
Commodore International. It was later released in August 1982 at a price of
US$595. The Commodore 64 is commonly referred to as the C64 (sometimes written C= 64 to mimic the Commodore company logo) and occasionally known as CBM 64 (Commodore Business Machines Model number 64), or VIC-64. It has also been affectionately nicknamed the "breadbox" and "bullnose" due to its shape.

<
computer> (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 Technolgies (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 to 16MB.
The C64's
1541 5.25
floppy disk drive had a
6502 processor as a
disk controller.
