It would be possible to prepare special software to make one work but you certainly don't want to attempt that yourself. The connector for the PS/2 mouse is different, I think, than the Mac printer and modem connector. I thought it was larger. It's certainly not electrically compatible. > > Ask if you need detailed pinouts. Ah thank you! I was way offbase with the mouse there hehe. This SE didn't come with a mouse, so I was just assuming that's where it went. I'll have to go on the look for one on the cheap then. I'd still love to get the pinouts for them though to add to my little database here. Thanks guys -- Compact Macs is sponsored by <http://lowendmac.com/>.
