I've not been working on this project for awhile (the kitchen took precedence).  I've traced the doorbell wiring to make sure that I hook it up to my circuit board correctly:

white - power wire (screw 1 on the front)

red - high chime

brown/red stripe - low chime

yellow - screw 3 on from (switch wire)

grey - med chime orange - ground?

sky blue - to chimes

brown - power wire (shared with white)

black - secondary chime wire.

Dark grey - neutral wire screw 5 on front
