Okay, got it home from the recycle center and plugged in. I know it has a hard drive installed, since I can see the activity light flashing and hear the disk rattle to life on bootup, and it attempts to boot from the drive, but can't actually boot; I get the question-mark disk icon. No big deal, I have install disks. The problem is, when I boot from floppies into System 6 or 7.5, it doesn't display a partition and can't find a valid SCSI device in Hard Disk SC Setup. Is there a way to figure out what's wrong, short of tracking down an ultra-long Torx screwdriver and opening the case for a look?
