Commodore C-128

 The Commodore 128 was launched at the Las-Vegas Consumer Electronic Show 1985. It was presented then as a competitor for the Apple Macintosh and IBM PC (The famous advertisement said "Bad news for Apple and IBM"). In fact, the only star of this show was the Atari 130 ST!

It is the successor of the Commodore 64 and can use all the software and a lot of the hardware of the C-64 (the


8502 can be slowed down 1 MHz for compatibility).

Thanks to the Z80, the Commodore 128 can run under CP/M +: lots of software was adapted for this computer and Osborne or Kaypro programs can run directly.

This machine was to have limited acceptance.
