I have an ISO image of it. let me get that up on my server for you

EDIT: This is the link. It's an image of my MacBench 4.0 CD (Yes, I own it, bought it off of eBay, it was not very cheap ($20+ shipping) as I wanted to test some stuff)

Keep in mind that some of the stuff won't work unless you have a really hi-res display (1152x876, etc..) and it requires minimum 12MB of RAM I think...

Either way, enjoy
