We suspected the original HD's may have been SCSI; but even with a SCSI HD installed they still do nothing except for the high pitched squeak the power supply makes when the main power switch is flipped. Does anyone here know if there is a way to undo these disabled Mac's. I know there not worth much but I figured I would give it a try.
Thanks!

It sounds like the ROMs are fried, too. When powered-up, even if the hard drive is missing, the opening screen should display as that screen is in ROM, if I remember correctly. Immediately after the opening screen a self-check begins and it does things like look for RAM, look for a HD, etc. If it finds the HD it should load the remainder of the boot OS from the drive into RAM.
If it fails at any stage after the opening screen it shows a "Sad Mac" face with an error code then the whole shebang locks-up. Write down the error code and go online and search for what it means.
But if you're not even getting to the opening screen, you got some serious doo-doo.
