Ok, followup.

I put a 1meg resistor across the osc1 and osc2 pins and it started working.   In Gunther Daubach book it shows a resistor (R2) on page 6 and the caption says "Depends on the resonator, or crystal type"

I'm using a two pin resonator (it does not have a middle ground pin).

Can anyone shed any light on WHY it works?
