Someone in another thread was asking about changing the 9150/80 from 2X the bus speed ( 2 X 40MHz = 80 MHz) to 3X and running the bus more slowly.

That was me, ojfd, I wanted to downclock several PM8100/100 and 110

Adding an ICS9178 is also how one converts the Turbo601/66 into a Turbo601/100 (well more like 90 to 96).

So, You're the one behind the Turbo601/66 chipping project mentioned on Schreier's page? If so, is it enough to just pull respective clock ratio pins on ICS9178 low or high to get the desired effect?

Btw, I'm interested in a couple of 9150 MB's as well, in case anyone reading this want to offload his. 80 or 120 doesn't matter. And I need them for REAL work, not just fun. I need PPC and more than 3 Nubus slots
