I am writing a program that is very sensitive to timing. Right after a picture is displayed, a routine which digitizes the operators voice is activated. Idealy, there is no delay, but a fixed <1ms delay is acceptable. Right now I am getting variable delay (~10ms). Is it the interrupts? I am not clear about the mac os. If I turn off the interrupts for the 68000 while this part of the program is running, will I ruin anything (assuming I don't care about keeping the tick count and time accurate?). Will the display suffer? If it is okay to turn off the interrupts, is there a convenient way to do this hi-level?. Thanks Doug Rosener biling@ucscd.BITNET biling@ucscd.ucsc.EDU
