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 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

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.[2] 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 ($1547 in 2024).[3] 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.[4][5]

Models

RS232 Serial and Centronics parallel printer ports are on the motherboard rather than on separate cards thereby making more slots available. it has one 5.25" floppy drive and no hard disk (can be installed). The PC 5 was released with MS-DOS 2.11 and GW Basic 3.2. The PC 5 had 5x 8-bit PC BUS Slots. It has two motherboards. One contains the CPU, RAM and ROM v. 2.01, an NPU socket and some VLSI chips. The second mainboard is connected by gold pin connectors, it is an "I/O board" containing serial and parallel port, ISA slots and all I/O chips. Some tracks from ISA slots are factory cut by drilling. The early PC10 has no RTC, HDD controller or reset switch, in front it has DIN keyboard connector
