First released in 1980 (Japan), the VIC-20 was an 8-bit home computer, made by Commodore Business Machines, that featured 5KB RAM and a MOS 6502 CPU. This was also the “first microcomputer to sell one million units.” Videos after the jump.
The VIC-20 had 5K of Ram, which netted down to 3.5K on startup, which is the equivalent to the words and spaces on one sheet of typing paper.
