orac original stepper drives

I am trying to interface a breakout board to the step and direction inputs on the original drives.

Could someone describe what is required.

is there a difference in how they process the incoming signal?

the step and direction points are in different places

What i need to know is what input are they expecting.

+5v +12v +24v

how much current is required.

12v, and if you do a search on here for digiplan there's a circuit describing how to drive the step and direction inputs from a parallel port
