[OT] Dead video card

Now that my memory is jogged, I recall that older PowerPC computers write data to the video cards in the opposite order that PC's did. Now that they have Intel based OS X systems for Mac, I think this has gone the way of the Dodo. But we are after all talking about an old G4. 

In fact, this was the reason that emulators like Virtual PC could never attain the performance on graphics intensive tasks that people needed. EVERYTHING graphics had to go through a translator. Nowadays, a lot of emulated tasks can access the processor directly with little or no translation, giving us the exceptional performance of emulators like VMWare and Parallels produces.
