The Commodore 64 was an 8-bit home computer introduced by Commodore Business Machines in 1982, as a successor to the VIC-20. It was named after the amount of RAM it had, 64 KB.
In it’s heyday between 1983-1986, it dominated the home computer market in the US and over 10,000 commercial software titles were available for it. Applications and games could be loaded from external cassette tape players, external disk drives, or through the Commodore 64’s built-in 44-pin cartridge expansion port.
In the US, aggressive pricing of the Commodore 64 was considered to be a cause of the video game crash of 1983 which led to the departure of Texas Instruments from the home computer market, along with other smaller game console manufacturers.
In the UK, the Commodore 64 was popular, but the ZX Spectrum was the market leader, selling for half the price of the Commodore 64.
In 1986, Commodore released the Commodore 64C in the sleeker style of the Commodore 128 and in 1990, the Commodore 64GS (Games System) was released, with the cartridge slot moved to the top and marketed as a games console. It was not a commercial success.
Demand for the Commodore 64 remained strong until 1990, and was finally discontinued in 1994, when Commodore filed for bankruptcy.
