Commodore PET 700

The commodore PET 700 is the first in the 700 series and is the same computer as the CBM 710 computer, but differently labeled for the European market. Both models are technically the same as the CBM 610, but in a case with detachable keyboard, and improved character graphics.

Commodore CBM 700 Series

The Commodore 700 series was introduced in 1982 and sold under a few different names. In the US they were sold as the B256 and PET 700 series, in Europe as the CBM 700 series, or CBM 256-80 / B256-80.

The hardware is identical to the CBM 600 series. The machines had an integrated monitor, detachable keyboard and two 5.25" disk drives. The BX256 model was capable of supporting an optional 8088 chip. Graphics and sound capabilities were also identical to the CBM series, except that the 700s had a new character generator ROM, and graphics were generated off an 8x14 matrix. The Kernal ROM determined which generator to use based on inputs that were hard-soldered on the main board.

MOS 6502 CPU

The 6502 is an 8-bit MicroProcessor designed by MOS Technology. The team was led by Chuck Peddle and had also worked on the Motorola 6800. The 6502 is a simplified, but faster and cheaper design than the 6800.

The 6502 was introduced in 1975 and was the cheapest microprocessor on the market. Together with the Zilog Z80, the 6502 helped start the home computer revolution of the 1980s. The 6502 was used in a wide range of devices: the Atari 2600, the 8-bit Atari home computers, the Apple II, the Nintendo Entertainment System, the Commodore 64, the BBC Micro and many others. All used the 6502 or a variation of it.

The 6502 is a 1MHz design, while the 6502A is designed for 2MHz. The 6502A is 100% compatible with the original 6502.

Commodore soon bought MOS Technology, but conitnued to sell the microprocessor to competitors and licensed the design to other manufacturers.
