HI All
I've got an ancient Bridgeport Boss-II running on LinuxCNC with a parallel port BOB board driving three equally ancient AH-HA SD124 stepper driver boards.
Does anyone have a manual or any other real resources for this mill and the Ah-Ha boards? Old Specification sheets, ANYTHING?

I'm looking specifically for specifications on the stepper motors used on the mill (current ratings, wiring, etc), and how to make sure the SD124's are set up correctly.
Also, anything that would help me diagnose problems with the SD124's.
