:-) I've installed UAE on my G3 Powerbook, and it works for some things, but it has problems. The emulated clock runs ridiculously fast, and it seems that the floating point unit is not emulated, or something. At any rate, Imagine will not run on it, though Magic Menu and Tools Manager work well enough, as do VisualPrefs and Birdie.
:-( I tried running PCX on MacUAE, (just for the sport of it, mind you.) but the Powerbook didn’t have enough real memory to give the Amiga enough emulated memory to run PCX.
