This doesn't seem to work correctly on the 3000. Hmm... I'll probably regret posting this, since the last time I did so, I got flamed to hell. (I am talking about reading/writing registers directly). It seems that a few C programmers would rather write a large quantity of code instead of just dealing with the info at the the source, i.e. registers. (No offense, C programmers). If someone knows how to toggle the filter in C, I would be interested in seeing the code.... Anyway, Here's how I have done it (not saying it is CORRECT, but it works nonetheless) ;-) filter_on: move.w #$7000,$bfe000 filter_off: move.w #$7002,$bfe000 >Thanks, > Aaron Hightower | ///| a.k.a.
