scratch install debian on iMac G3

[Steve Richter <StephenRichter@gmail.com>]

I have an iMac G3 ( OS 9.2 ) newly arrived via ebay. The system did
not come with the system disks, so I do not have the Drive Setup
software I think I need to create a 2nd partition on the Mac to
install Debian into.

To install debian on this iMac do I have any options other than the
purchase of the OS 9 CDs?    I dont need to keep the Mac OS on the
system.  Is it possible to scratch the OS from this system and replace
it with Debian GNU/Linux?

thanks,

Steve Richter
