Here's the two Macs I spoke of earlier-the Quadra 700 and the Beige G3.
Before removing them, I powered both on. The Quadra booted right to a System 7.5 desktop. The G3 got stuck on the "happy mac" but I'm sure it's nothing insurmountable to fix.
As I mentioned, the Quadra had an AEKII with it, and the G3 and Appledesign keyboard. The Quadra also was attached to an AAUI to 10baseT bridge, as well as a SCSI ZIP drive. Plus, both computer had Appletalk boxes and cables attached, so I can network them to my other old Macs
I also checked out, but did tamper with, the SGI system, and it is indeed an Octane. I talked to two of the users with accounts on it, and both said that they probably hadn't used it in at least 10 years and didn't remember their passwords. The third user is in Poland now.
I probably should start a new thread for this, but as I understand it I can install OS 8 on the Quadra. I have a factory install CD, but the big issue is that the Quadra doesn't have a CD-ROM drive(and I don't have any external SCSI drives). If I made an image of the CD-ROM I have, does anyone know if it would be small enough to restore to a 100mb ZIP disk?
And, since this thread has turned into "pics or it didn't happen"

, here they are:
