Just a FYI, XPostFacto has beta-level support for 10.2. I got it running on my 9600/300, so it looks like there still is future support for my beloved old macs.
B&W's are supported so you won't need anything extra there. It's pretty much for the non-stock-g3 desktops and laptops based off the PCI architecture. The machines w/the best support are in the 7300-9600 (and clones of these) range.
