The 133MHz bus Apple processors (from Quicksilvers and Digital Audios) are "usable" in your Sawtooth with the following issues: 1) QS processors will need an additional 12v line brought to it. Fairly easy to do 2) The QS and DA processors have a different form factor than a Sawtooth's, so to use one you need to remove one of the onboard IDE/ ATA connectors. Difficult to do and a bummer to lose one channel. 3) The processor will only run at 100MHz speed with the built in multiplier. So that a 733 processor will run at 550MHz. Bummer speed drop.
