If ever you write a little app (or mod of the existing one) that can take advantage of the 68881 and 68882 FPUs, that would be really amazing! The Levco SuperMac SpeedCard I have now is having 68881 FPU issues. To be honest, I'm not sure if it is working. Neither Speedometer nor Norton System Info recognize its FPU chip, and yet a friend of mine told me his Radius accelerator (also used in a Mac SE) shows his FPU just fine in both apps. So having a nifty little app to test the FPU would probably be a help to any 68K owner who has an accelerator of some sort, or who has a 68K Mac with a built-in FPU.
