How to remove OS9

[Arjan Bos]

Dear list,

I'm in the fortunate position that my TiBook is capable of booting into 
OS9. I did it once, out of curiosity, but finder crashed and made me 
reboot. Since then I left it on my system for the odd classic app.

In the past few months, my 30GB harddrive filled itself up nicely and 
since I noticed that I do not have any classic app without an OSX 
replacement, I decided to remove OS9 from my machine.

Could any of you please inform me what to remove? Since I've never 
worked with OS9 (this TiBook is my first Mac), I'm not sure which files 
and folders are involved. How do I find out?

TIA,

Arjan
