Correction: the difference is the PowerPC CPU *and* the PPC<->68k bridge chip.

My PowerMac 5200 uses a design almost identical to a PPC upgraded Q630, and
the big stumbling blocks I've hit (in porting linux) are a: modifying bootx
to tell me I'm not on a real powermac (I don't have codewarrior) and b:
grokking the undocumented weirdness of the bridge chip.

There's also other fun little details, like the 5200 (and assumably 68k
upgrades) are, unlike an untouched 68k or real powermac, not
cache-coherent, though that shouldn't affect *too* too much.

Anyways, that's the short answer. For the long answer, ask David Gatwood. :)


Cheers - Tony :)
