Stopping the clock on a 68000 system

[Uriah]

I have this in-circuit IC tester that requires that I stop the clock by
removing the cpu which I can't do because it is soldered in. How would
I go about stopping the clock in a safe way? This is a arcade game
board and has a few cristals on it. Do I just ground the clock off of
the cpu or can I ground one of the pins off of the cristal? There are
a few CPU's on this board. One 68000 and one Z80.
Thanks for the help

Don't start grounding pins off of the oscillator, or you may blow it.
Try removing the crystals form each microprocessor. prior to testing.

Will using the "Hault" pin on the cpu stop the clock on the whole
system? And do I just ground it or do I have to use a resistor or some
other way to get that pin low. This is on the 68000. Thanks for the
help
