I'm currently using single ended to differential converter boards that I made for the step-direction and encoder signals. Each axis requires a separate board and the result is a rats nest of wires. I'd like to layout a new board that plugs into the USC directly and handles the conversions for all four axis. Can I get the locations of the stepper and encoder headers?

An unrelated question: If I program the timer register to latch the encoder counts does the USC also set the parallel port interrupt signal?

Well, I can supply that. But, the connectors are 3.81mm connectors from On-Shore Tech.
I'm not exactly sure how to get the connector coordinates out of the CAD system, but maybe just the coords of pin 1 will do?

Yes, it will generate about a 2 us pulse on the /INTR pin # 10.

OK, with the lower left corner as (0,0) the leftmost pin of P3 is (1.894, 0.430) and the rightmost pin of P2 is (3.614, 3.866).
P6 left is (4.450, 0.426) P7 left is (7.070 , 0.426) P4 right is (8.194, 3.866) P5 right is (6.234, 3.866)
Well, J2 and J3 are just the same pins as P2 andP3, and I didn't think anyone used them. Lately, I have not even stuffed those, and nobody complained. I'll get the coords later.
