The Commodore 128 (C128, CBM 128, C=128) home/personal computer was the last 8-bit machine commercially released by Commodore Business Machines (CBM). Introduced in January 1985 at the CES in Las Vegas, it appeared three years after its predecessor, the bestselling Commodore 64.
The C128 was a significantly expanded successor to the C64 and unlike the earlier Commodore Plus/4, nearly full compatibility with the C64 was retained, in both hardware and software. The new machine featured 128 kB of RAM, in two 64 kB banks and an 80-column RGBI video output (driven by the 8563 VDC chip with 16 kB dedicated video RAM), as well as a substantially redesigned case and keyboard. Also included was a Zilog Z80 CPU which allowed the C128 to run CP/M, as an alternate to the usual Commodore BASIC environment. The presence of the Z80 and the huge CP/M software library it brought, coupled with the C64's software library, gave the C128 one of the broadest ranges of available software among its competitors.
The primary hardware designer of the C128 was Bil Herd, who had worked on the Plus/4. Other hardware engineers were Dave Haynie and Frank Palaia, while the IC design work was done by Dave DiOrio. The main Commodore system software was developed by Fred Bowen and Terry Ryan, while the CP/M subsystem was developed by Von Ertwine.
