Description:The Commodore 64 was a home computer Commodore Business Machines Inc. sold from 1982 to 1993 in various states of the world. Born as an evolution of the Commodore VIC-20, and can offer better sound and graphics capability than the Commodore VIC-20 at the expense of compatibility software, they have been marketed several variations. Evolutions were instead the Commodore 128, Commodore 128D and the Commodore 65, all in software compatible with the Commodore 64. The first two have been marketed since 1985, the third remained at the prototype stage, and production ceased in 1992. In 2004, the company launched a machine inspired by the famous home computer: the Commodore 64 DTV.
Specs:Cpu: MOS Technology 6510/8500 @ 1.023 MHz (NTSC version) @ 0.985 MHz (PAL version)
Memory: 64 KByte
Video-Card: VIC-II (320 × 200, 16 colors, sprites, raster interrupt)
Effect:The Commodore 64 had a chip video (VIC-II) that could produce 16 colors (The optical illusion of a larger number of colors was obtained with special software algorithms). It had a maximum resolution of 320 x 200 points in the "hi-res" (2 possible colors for each cell 8 x 8), and 160 x 200 as "multicolor" (4 possible colors for each cell 4 x 8, with pixels wide double). The text mode provided a display of 40 columns by 25 rows. The font of default was changed (it was enough to order the graphic circuit to pull definitions of characters from RAM rather than from the ROM). The chip ran up to 8 hardware sprites, ie graphic shapes easily manageable from the chip to obtain images and animations, drawn above the conventional screen.
