As far as I know, no one's hooked one up to an Amiga just yet. The approach you'd probably take is to write a task that sits in the input stream. As events are recognized as coming from the bitpad, your task translates these into mouse events. This is all happening at a reasonably high level; it's not like you actually have to turn bitpad signals into mouse quad signals or anything. You're going to have to play some trick, I think, to translate between the absolute positioning of the bitpad and the relative positioning of the mouse. Once this driver is installed, though, it should work for any Intuition application. I think I've seen an example of something like this around, but I can't recall what it was called. > Keith Doyle > # {ucbvax,ihnp4,decvax}!trwrb!cadovax!keithd > # cadovax!keithd@ucla-locus.arpa Contel Business Systems 213-323-8170 -- Dave Haynie Commodore-Amiga Usenet: {ihnp4|caip|rutgers}!cbmvax!daveh "The A2000 Guy" PLINK : D-DAVE H BIX : hazy "Catch a wave and you're sittin' on top of the world" -Beach Boys
