Ok, We have some old Mac LC II's and LC III's. We want to Nuke the hard drive using a floppy disk, but inorder to do that we need the Mac to boot to the disk and I'm not sure how to do that. If any of you guys have experience with Older Macs and would like to help someone out I'd appreciate it.

Thanks!!
 
You need a startup disk. I assume you have the OS on floppies to reinstall an OS, well the first one will be bootable and will have the "Drive Setup" utility on it which you use to erase the hard drive.
 
thanks I'm going to check them right now. We have a Drive erase disk already, but if it's on a system disk, that'd be a lot easier.
 
Wow. Thanks for the memories. Those big plastic wallets with all the diskettes inside :)
 
Hmm. Try CMD+OPTION+SHIFT+DELETE at startup. Apparently that used to work on a Quadra.
 
Change the startup disk in the Control Panels to the floppy.
Or..
If there's no valid OS to boot from, it'll boot to a valid OS on a floppy by default.

hmmm, it didn't work. but thanks a lot for the help. I'm willing to try anything... maybe even a baseball bat
 
Maybe there's something wrong with your boot floppy. Could you try making a new one?

This is a System 7.5.3 boot disk image you could copy onto a floppy.
