The Commodore 64 (commonly abbreviated to C64 or C=64) is an 8-bit home computer system launched in January 1982 by Commodore. The platform took its name from the 64 kilobytes of RAM that it boasted and at a launch price of $595 was well below that of competitor the Apple II.
Between 1983 and 1986, the Commodore 64 dominated the market outselling the IMB PCs, Apple computers and Atari 8-bit computers with sales peaking at more than 400,000 per month.
