The 10mhz oscillator is right next to the cpu. The replacement 15mhz oscillator is a older style package(through hole), but the pin out is the same, might have to solder 4 legs on the oscillator if the leads are not long enough to touch the proper pads.

You can remove the old oscillator, or you can "by-pass" it and just attach the new oscillator to its legs,

kind of how a clock chip clip thingie works. I've never done it the bypass way, I just remove the old oscillator with 2 soldering irons.

I already installed the inductor and oscillator mod for the Sonic Networking IC. So it could have its own (10 MHZ Clock) derived from a 20mhz oscillator, separate from the CPU.

Basically with the Centris 610 model /w networking, the cpu and the networking I/C shared the same 10mhz clock from the cpu, to save cost.
