Those should be good, Ed. When trying to measure resistance in a circuit
containing semiconductor junctions, DMMs voltage can sometimes alter
readings a bit. You are within 10%.

Many DMMs give no reading at all when seeing an open circuit. What does you
DMM do in resistance scale with the leads not touching anything?

I have some questions on the results of my check.  
U6 pin 29 should read between 70 and 90k, I'm reading 96k.
U6 pin 30 should read between 70 and 90k, I'm reading 97k.
U8 pin 15 and 16 should read >100k, I'm not getting a reading at all so I'm
wondering if this is the way my DMM reads infinity.

Are these readings in the ball park or do I have some trouble some where?
