It's a cheap way of getting a clock. phi2 pin is AFAIK a copy of what the 6510 gives out to the rest of the system, so when the 6510 gets halted by the VIC-II... is phi2 affected? DOT clock is AFAIK a copy of what the VIC-II is given by the clock circuit or the 8701 chip, so it's not affected at all by the VIC-II dictatorship. What would someone like to have constantly running at DOT speed no matter what happens inside the C64? > > This used it for that exact reason > https://retrotinker.net/cpm-card-with-8mhz-for-c64/ > > ~8mhz is kinda high for a sound chip though.
