Hey Everyone,
I browsed the winamp plugin library and found a little porgram called COM-port Winamp Control. Basically it lets you connect up to 15 buttons to a 9 pin com port. I've build a little control box out of an old floppy disk case that has the following functions: Previous Track, Play, Pause, Stop, Next Track, Volume Up, Volume Down. You can see a picture of what it looks like here:

So anyway, this could be a nice feature to have on a mame cab or jukebox to change music and whatnot. Just throwing it out there
