Hi Norman,
I had to piece this guy appart a few months ago and wrote down the board schematics. I can send you what I have but it has not been curated at all.
I found your post trying to figure out what the dip switch do... The X, Y, Z axis have 3,4,5,7 ON; The A axis has 3,4 ON.
From left to right on the Green 6 screw terminal you have: A-, A+, B-, B+, V+, GND these connect to your stepper and power supply
The white terminal connects to the through hole labelled ENA, 5V, DIR, 5V, P, 5V and go to the parallel card adapter.
