Laptop wise: it's a PowerBook G4 1Ghz 15', Titanium model. Desktop: PowerMac G4 Tower, MDD version.

Currently my "big" native 9.2.2 system is a MDD G4 with a Sonnet 1.8GHz dual 7447A upgrade, 2GB RAM (1.5GB useable in OS 9) and an ATI Radeon 9000 Pro. I'm sure there's a config more extreme than that out there. It is a pleasure to use even though it's one of the windtunnel systems.

Quite a lot. I remember my dad's SE(?) could be upgraded to 128mb ram or some ludicrous figure, compared to my 8mb 486.

Officially? A single cpu G4 tower. Beyond that, I'm not sure.
