It also had a hardware frequency filter and ADSR (attack, delay, sustain, release) volume envelopes and was very advanced for its time. The VIC-II chip supported 320×200 monochrome and 160×200 multi-colour video modes, 16 colours and could manage 8 24×21 (or 12×21 colour) pixel sprites, – independent graphics objects – and detect collisions between them. ![]() The Commodore 64’s 40-column screen was much easier to read than the VIC-20’s. The new project was dubbed the VIC-40 but renamed the C64 in time for CES. However, after the chips were completed, several Commodore engineers disagreed with the project’s direction, insisting that the company should instead develop a successor to the VIC-20, Commodore’s low-cost computer, not a console.Ĭommodore CEO Jack Tramiel opted to go ahead with both projects, however he insisted the computer come with 64 kilobytes of RAM in order to make business applications more practical than they were on the memory-starved VIC-20. ![]() ![]() ![]() In early 1981, Commodore-subsidiary MOS Technology began work on graphics and sound chips for a next-generation video-game console called the Ultimax, thinking that was where the company’s future lay. The Commodore 64, introduced at the 1982 Winter Consumer Electronics Show, was a significant improvement on the VIC-20, and would become the best-selling computer model of all time. ![]()
