I have no idea. It originally shipped with *shudders* 16 MB of RAM, but I don't know if the previous owner upgraded it or not. I'd really prefer to run System 7 or OS 8 if possible. I like my computers to be speedy, even if it means using a slightly outdated operating system.

I just realized I posted this in the NuBus forum by mistake. My Power Mac is a PCI model.
