C64C

The C64C, short for Commodore 64 C, is a redesigned variant of the Commodore 64 home computer. It was introduced by Commodore International in 1986 and sold through the late 1980s. The casing was redesigned into a slim, integrated plastic chassis replacing the original breadbox enclosure, giving the unit a more compact appearance. The internal motherboard was revised (often referred to as the C64C board) while retaining the core 8-bit architecture of the C64.

Hardware-wise, the C64C uses the same 6510-compatible central processor running at approximately 1 MHz in PAL regions and clocks appropriate for NTSC regions, and it includes the same VIC-II graphics chip and 64 KB of RAM in standard configurations. The machine remains compatible with the broad library of C64 software and with standard peripherals such as cartridges, datasette, disk drives, and joysticks.

I/O and connectors: The C64C preserves the typical C64 user port, expansion bus, cartridge slot, joystick ports, and video outputs, including composite video output and RF modulated output, with regional differences in connector arrangements. The power supply remains external, and the unit shares the same power characteristics as other C64 models.

Impact and availability: The C64C was produced during the late 1980s as Commodore shifted production toward a lower-cost, more compact chassis. It is often viewed as the final major hardware revision of the Commodore 64 line before Commodore's dissolution in the early 1990s. Today, the C64C is considered a notable variant among collectors and retrocomputing enthusiasts.
