Possibly.  I stopped using MacOS around 8.0, so I really don't know much
about the old MacOS.  I started using Linux and *BSD because I could get
a real terminal window, which MacOS never offered.

The last two Macs I purchased had OS 9 and OS X pre-installed, and
booted into OS X by default.  I don't know the secret magic key sequence
to boot into OS 9, so I never booted into it.

I reinstalled Jaguar on one of my macs about 7-8 months ago, and it
looked like it was attempting to install OS 9 for Classic (before I
stopped it).  

For the record, if you format a disk for HFS+ and *don't* put the MacOS
extension partitions in the front of the drive, OS9 and Classic can't be
installed; installing OS X goes faster because it doesn't install two
OSes at once.  :-)

Both use HFS+, so just installing it on an existing 8.6 partition shouldn't
be an issue.  Just make sure you back everything up first.  :-)
