Summary: How to I calibrate a Vax750 clock

Being able to synchronize all systems to the same time is nice.  Having
that time be the correct time is even nicer.  I have several Vax750s and
a Vax785 who's clocks run fast.  By selecting systems with better clocks
to be the masters I can work around this but the result is not ideal.

Does anybody know where to adjust the real-time clock on a Vax?  I could
probably come up with an accurate frequency counter or just keep
tweeking it until it is right but I can't find the crystal, much less a
trimmer for it.
