The first 3 have 32 and the last 64 Mb of RAM in the same ATI 9200 that is the last ATI (at least the PCI one) that has Mac OS 9 drivers.

As MacTron said, it should need some open firmware commands to allow those 7447a proc. run in 9.

Is the northbridge, MPX, MaxBuss chipset the same than on MDD/iMac G4?
