I'm currently writing a program, for which I need some very accurately timed sound routines. I am thinking of speeding up the oscillator, by programming port 0 of the timer chip, and then write a new INT08 interrupt handler, that say only calls the original INT08 every fourth time (just like some Basic versions does). However I have never tampered with port 0 of the timer chip, so I was wondering if anyone out there could help me out with my problem. THANKS!! email : efa@iesd.auc.dk (Erik F. Andersen)
