| Why does my 33MHz 040 equipped Centris 650 Logic board say 25MHz |

What do I need to do to get it to 33MHz?
Thanks

You need a 16.667 MHz oscillator...

I think there's a resistor moving hack for the Centris/Quadra, isn't. Let's see...
Oh, nope, it's an oscillator modification. Happily, Applefool is mirroring Marc Schrier's old Clock Chipping Home Page. But there are resistor modifications that may be necessary for the serial ports to operate properly at 33 MHz.

The Quadra and Centris 650 share the same logic board, so it is possible. Hmm
