The Commodore PC compatible systems are a range of IBM PC compatible personal computers introduced in 1984 by home computer manufacturer Commodore Business Machines.

Incompatible with Commodore's prior Commodore 64 and Amiga architectures, they were generally regarded as good, serviceable workhorse PCs with nothing spectacular about them, but the well-established Commodore name was seen as a competitive asset.[1]

History[edit]

In 1984 Commodore signed a deal with Intel to second source manufacture the Intel 8088 CPU used in the IBM PC, along with a license to manufacture a computer based on the Dynalogic Hyperion. It is unknown whether any of these systems were produced or sold.

In 1984 the first model released, the PC-10, sold for $559 without monitor ($1273 in 2020).[2] They were sold alongside Commodore's Amiga and Commodore 64c/128 lines of home and graphics computers. The PC10 was comparable in the market to the Blue Chip PC, Leading Edge Model D and Tandy 1000 line of PC compatibles.[3][4]
