No Mac OS CD - What Now?

[John Kim]

I salvaged an old 7500/100 running OS 8.5 for the sole purpose of running
Linux. I don't have the Mac OS Installation CD. What can I do? Is there some
place where I can download the CD image of OS 8.5?

Also, the "Installation Guide" says to install OS 9 on one of the
partitions -- can I use OS 8.5 instead?  At this point, I don't know where
I'm going to get my hands on either OS 8.5 or OS 9 CD. I just thought the
older one (8.5) might be easier to obtain freely.

Thanks for any ideas/suggestions,

-John
