Just had a quick question I was discussing with some friends of mine. Are macintoshes currently using risc or cisc architecture?
Thanks,
Venkman

RISC since 1994, with the IBM 601 (Generation 1)
next was the 603 and 604 in 1995 (G2)
in 1997 we had the 750 (G3)

we have now been on G4 7400, 7410, 7450 and 7455 for some time

I tried to remain child-like, all I acheived was childish.

I think we made the jump to risc processing when Apple moved from 68k machines to PowerPC, that was years ago, like 1994 or so.

By the way, here are some articles on a likely next generation PPC CPU, the IBM 970
