Peter:

Any CMOS/TTL clock oscillator (the Epson, CTS, or ECS oscillators
available from Digi-Key, for example) should work just fine.  Note
that some of them have an "Enable" input on pin 1... You don't need
those.

In general, you'll have more reliable results if you use an
oscillator on the PIC-Probe rather than one on the target board...
Those high-speed clock signals don't like traveling through the
18-inch Pod-to-Probe cable.
