Flashback: MOS6572 VIC-II Timings

In Flashback I present selected posts recycled from the first iteration of SolidState blog.


Argentina was the only place in the world where Commodore allowed it’s computers to be license built and co-branded with the local manufacturer, that manufacturer being Drean.

Commodore models assembled by Drean were the Commodore 16, the C64 and the C64C. They also sold the C128 but it was only a rebadged NTSC C128.

The other thing unique about the Drean Commodore computers was the use PAL-N as video standard.

The PAL-N standard uses almost the same audio carrier that the NTSC standard, this prevented the use of the PAL-B versions of the TED and VIC-II chips.

Therefore, Commodore manufactured special PAL-N versions of both TED and VIC-II chips, this article is about the later.



The PAL-N version of the VIC-II is denominated MOS6572 and to this day there’s only two revisions known of:

  • R0 – Ceramic package
  • R1 – Plastic package

As all the C64 clocks are derived from the same single crystal and generated mostly by the VIC-II, the different audio carrier frequency called not only for a new video chip, but also a new crystal.

As we will find later, the crystal used on the Drean C64 is of 14.328224 MHz.
