> So, where do you buy a scroll wheel WITHOUT a mouse? Do they need the scroll wheel function for a PC - ie used as it was intended, or is this for some other non-PC application ? IOW, do you need the scroll wheel with the signal-generating micro ? What quantities ? If this were for just a few I'd try a service centre or large (eg office) company and ask for mice that have gone in the bin. Very often the only fault is a broken wire and that isn't worth the time or effort to repair -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
