COMMODORE  VIC-20

The VIC-20 (a.k.a. VC-20 in Europe) was first shown in the 1981. The VIC-I was video chip, designed by Commodore two years prior to the design of the computer. It was originally meant to be sold to third-party manufacturers, for use in video game machines. No one wanted to use it, so Commodore decided to make their own system and recoup their losses. VIC-20 featured 6502 microprocessor and 5 (max. 32) KB RAM.

COMMODORE  64

Designed in 1984, the C64 (on the picture) was the follow-up to the successful VIC-20 and became even more popular. It came with a new sound chip, better graphics and even a disk drive was released for it. The machine went on to becoming probably the best selling single format computer in the world. It was powered by 6510 CPU and 64 KB RAM. The C128 (1985) was similar to C64 - it offered faster speed, better graphics, 128 (max. 512) KB RAM and Z80A CPU, along with 8510, to run CP/M operating system.

COMMODORE  PLUS/4

In 1984, Commodore attempted to follow the success of its previous models with introduction of C16 (7501 CPU, 16 KB RAM) and the C116 (a budget version of C16 with the rubber keyboard) computers. This attempt of 1984 also include the Commodore Plus/4 (on the picture). It came with four applications in ROM: word processor, spreadsheet, graphic software and database. It also featured an improved Basic with graphic and sound instructions and a built-in assembler, but had lost many interesting C64 features, like soundchip or hardware sprites. Plus/4 was based on 7501 CPU and 64 KB RAM.
