MicroPython support (Christine) came to the rescue.
She provided the proper pin connections to ensure that the board is operational:
//
On the right side of your pyboard you'll find the Pins named: X4, Y9, Y10, GND and V+. If you put a LCD right next to it, you'll find the same names of Pins on the PCB of the LCD.
Python test code:
>>> import lcd160cr
>>> lcd = lcd160cr.LCD160CR('XY')
//
I have attached a photo of the setup for others reference.
