Do not try and put OSX on a 233/g3. It will be dog slow!!!. on top of that it probably has a really old and slow graphics chipset. If you want that machine to be decent then take the advice of the good people here and get it up to OS 9.2.
PS: the tray loading imacs have problems with burned CD's
PSS: classic MacOS, co-operative multitasking in the year 1999 :-o . The Amiga had pre-emptive in 1985 :-D
