This value is such that: system clock (about 1 million) ticks_per_second (about 60) = --------------------------- (LOC+1)*256 + (LOC) By adjusting the contents of those locations via POKEs, you should be able to adjust the clock speed. Use smaller values for faster, larger values for slower. I can't guarantee that these locations exist, but I'd give you 10-to-1 odds on it. They could be in ROM, where you can't change them even if you find them -- you might try changing the VIA directly in that case. Good Luck! Doug Pardee -- Terak Corp. -- ...!noao!terak!doug
