I know this is kind of a copy of my post on the 68kMLA Forum but I just thought I'd let everyone know that I picked up a few more PowerBooks. I just thought I might let everyone know about my recent actual liberation, from NAU's surplus store, two members of the 500 series of PowerBooks.
The 520: 20 megs of ram, 120-ish meg hdd.
The 520c: 36 megs of ram, 1000-ish meg hdd. Global Village Modem.
Both are running system 7.5, and both are (other than the hinges and batteries) fully working. Which really surprised me, for $10-for-both from a university surplus sales store.
Once I get home for the summer I'm probably going to reformat them a bit and put clean installs of some older software on them. I might try to find the 520/520c original install discs and drop 7.1 on them, not completely sure yet. My other project with these machines will be to fix the hinge a bit on the 520c, and to see if I can't get any life at all out of the batteries. I may also try to source a second power adapter, because right now both 520s are sharing the same adapter.
Another interesting tidbit: These machines still had user data on them, research from the French department on this campus, I believe. It's all French stuff though, I don't even know if any of it was typed in English, so it's not terribly interesting to look at, or read.
I'm pretty excited about these machines and the 180, it's nice to be able to have some 68k power with me here at the university. This summer, I intend to try to find some more of my software and accessories for PowerBooks. I'm sure I've got an HDI30 adapter, and I'll probably bring back the external scsi hard disc, and-slash-or the USB floppy drive.
