I am using a G4 quicksilver running leopard. It has two hard drives. I have some older programs that I would like to be able to run that require classic and ran well in 8.6 on my old iMac that died. Can I use the install disc from the iMac and install 8.6 on the second drive without hurting any of the system stuff on the first drive?

Yes, sure. But I'm not sure what options were available on the 8.6 install disks. You may have to clear the 2nd drive completely, then install 8.6. Then you can continue to store things on the second drive and access them when booted into OS X.
I'm curious -- what OS 8.6 programs do you still use? There are no newer versions or replacements for these in OS X?
