That should take 2 PC133 SODIMs. 256M should be ok. You may have to find
ones that use 128M chips instead of 256, but that varies from model to 
model. See what's in there, it may take PC100.

Just make sure it does does not have trap door on the back. If it has a memory
door on the back, it takes regular SDRAM (PC133) DIMMs.

Sorry, don't remember. It could be either. If it does not like the RAM at all,
it will ignore it or not boot. If the chips are too high a density, it will
use what it can.

If it has firewire ports, it will run tiger out of the box. You will have to
get a copy of the CD version to do the install. 

Before you do, upgrade the firmware for OSX. This needs to be done by placing
the upgrade on a writable OS9 disk and booting from that disk. The upgrade 
is probably on your OS 9.1 CD, or can be downloaded from Apple.

Except for historical reasons, 10.3 is not worth persuing. There really were
big changes between 10.3 and 10.4.
