I am continuing the debug process from last night. I verified the 2
MHz CLOCK signal is still almost zero volts on the NorthStar

voltage than 0 but will have to double check what is going on with it.

It sounds like your trying to measure this with a DMM and that won't work.
Not only will digital meters not average, but a high frequency signal will
screw
them up even if there is some fixed DC component present. They're really
not
much use around computer circuitry except for reading power supply voltages.

As others have said, you really need an oscilloscope.
