Well, so what's keeping you from doing it the right way? :-) >Actually, if you are talking about Intuitracker, you're dead wrong, because >IntuiTracker uses the Vertical Blank interrupt, and not CIAs at all. So it does: 0002ccd8 0002ccf8 0002cd50 10 S E Vert.Blank IntuiTracker (from xoper) I have source to another tracker that uses vblank, and it doesn't crash the system during serial I/O. As I understand it, using the VBLANK int for this sort of thing is not considered a good idea. The overhead is very high, and you run into the PAL vs. NTSC timing thing. -- | ben@epmooch.UUCP (Ben Mesander) | "Cash is more important than | | ben%servalan.UUCP@uokmax.ecn.uoknor.edu | your mother." - Al Shugart, | | !chinet!uokmax!servalan!epmooch!ben | CEO, Seagate Technologies |
