Hi there, before I bolt up the HP 45 and replace the back label I was wondering if anyone has done the timer to quartz timer conversion as posted here:

If so, I have a few questions:
Has anyone done this conversion?
Where would you find a 784 kHz crystal?
Is the HP 55 crystal also a 784 kHz crystal?
Cheers and thanks in advance, Geoff.
