I know this subject has been hit from many directions but would someone let me know if there are incompatibilities with speed doubler and FB. I just picked up a 7200/80 and have 0S8.0 loaded. I really don't see that compiles are quicker although the compiled program is definitely quicker. I would like the compiler to be able to take advantage of my new found speed. Hey, no laughing. I just moved up from a Quadra 605. If I had some real cash I'd have bought G3 something or other. :D Thanks, W.
