There is no such thing as a 68060 - The last one was the 050.

The last one macs used was the 040

A quick search of my HD found an 8.0 installer, it's being uploaded right now. I will post the link when it's done

EDIT: I just remembered that there is a Myst CD in one of my stacks of disks... dunno if its 68k compatible, though.
