The board is from the front display. 1 STC, one 7 seg display driver, 2
encoders and a few buttons. Physically they are identical. I think the power
board that this talks to is not completely compatible with Ver 4.

For a start the old board displays Amps and Volts on 2 sets of 7 seg displays,
the new Amps and a range of -5+5 units. 

There are only 7 wires between the two boards so I might take a look at the
signals.
