Commodore 64

The Commodore 64, also known as the C64 or the CBM 64, is an 8-bit home computer introduced in January 1982 by Commodore International (first shown at the Consumer Electronics Show, January 7–10, 1982, in Las Vegas).[4]  It has been listed in the Guinness World Records as the highest-selling single computer model of all time,[5]  with independent estimates placing the number sold between 12.5 and 17 million units.[2]  This claim is in spite of the Commodore 64 having three different Kernal ROM versions, two different SID sound chip versions, a few different motherboard versions and two different cases during its lifetime.[6]  Volume production started in early 1982, marketing in August for US$595 (equivalent to $1,576 in 2019).[7] [8]  Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes (65,536 bytes) of RAM. With support for multicolor sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware.
