VIC-II Kawari – Commodore 64 VIC-II 6567/6569 – Replacement

VIC-II Kawari is a hardware replacement for the VIC-II (Video Interface Chip II) found in Commodore 64 home computers. In addition to being compatible with the original VIC-II 6567/6569 chips, some extra features are also available.

The PCB interfaces with a real C64 address and data bus through the VIC-II socket on the C64 motherboard. The board can replace all the functions of a real VIC-II chip including DRAM refresh, light pen interrupts (real CRT only), PHI2 clock source for the CPU and, of course, video output. It’s ideal for resurrecting a C64 with a faulty VIC-II chip, or for adding better image quality to the C64 or more flexible video output options.

Compatible motherboard Revisions:

  • Suitable for 250407, 326298, 250425 & KU-14194HB* motherboards (all “breadbin” and some C64C revisions, see note below).

NOTE: For 250425 boards, the large RF shield that sits under the keyboard should be left out. For the other revisions, the cover of the RF shield enclosure must be removed.

All purchases come pre-installed with an extra socket to give the board enough height to clear motherboard components.

  • Due to the narrow RF shield surrounding the VIC-II socket on this model, an additional socket may be required for the large model (not included).
