1985.

Commodore 128 was a direct successor to Commodore 64. It was, however, not as popular. Almost all applications from the C 64 could run on the C 128. Also most of the hardware. This is because you could convert it to the C64-mode. Not only that, thanks to the second processor - Zilog Z80 - you could also run CP/M. There were a further amount of programs that could be used. Inter alia the Osborne-programs could run directly. It had three positions - Commodore 128, Commodore 64 and CP/M.
Later came a version with separate keyboard and built-in disk drive in the main unit, Commodore 128D.

Thanks to Anders Persson, Anders Datormuseum and to Christian Johansson, Commodore 64 - "datorernas folkvagn" for valuable comments.
