Most of the software packages will have the pinouts. I have seen that most control boards use a standard for x, y and z axis. Some, like Mach, let you configure all the pins to match non standard pinouts.

Good luck with resurrecting your machines. They look fairly new so should be adaptable. The control system for my router had a 25 pin serial port and the software was not available. I was able to wire a new control system to the existing steppers.
