Commodore CBM 3008 - Overview
The CBM 3008 was released in 1979 and ran a 6502 CPU at 1MHz, had 8KByte of RAM and a built in black and white 40x25 text monitor of 9".
The Commodore CBM 3008 was a direct descendent of the PET 2001. The 3008 uses the same board as the 4000 PET series, but caries BASIC 2.0, which is the identical version found in the VIC-20 and the C64. The Commodore 3008 did not last long. It's limited 8K RAM was quickly upgraded and the machine was replaced with the 3016 and the 3032.
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.Source: WikiPedia - MOS Technology 6502
