There's more than one out there, but I've already got one of each of the types available, so I just took the one. Most of this stuff comes from the educational institutions in the surrounding area, and the college is pretty well funded, so they change stuff out pretty often.
They're already getting a few MacBooks and stuff out there, though most are in pieces. No G5s yet, though. There's an Amiga 2000 out there that I might get, along with a PC/XT. More toys than I could ever handle.
The place is privately owned, but I work there for a few hours, and instead of getting cash, I get Macs and whatever random junk they were just gonna toss. It's a sweet deal. Better than eBay, anyway.
