Cool. I just dug my SparcClassic out and am trying to decide what I want to do with it. It powers up, but I can't really test it because I don't have a Sun monitor or a 13W3 adapter. I think the Sun keyboard and mouse are also proprietary.

On the bright side, the old lunchboxes use 50 pin SCSI devices, so if you have a lot of stuff leftover from old Macs, it might work on the Sun if the Apple ROM chip doesn't decide to get in the way.
