Hi Chris
I think I know why that board had been put away and forgotten.
I got one for experimenting and it is basically not much use to drive a scope as is. The software is very basic and will either rotate the stepper cw or ccw up to about 760 pps. That is about all.
To interface it into a telescope drive program will require two boards and connection of the second board to the unused data lines of the Printer socket.
The program will then need to have a second set of commands to drive the second board in the same manner as before.
When this is done the lot can be interfaced into some sort of telescope drive program. eg Bartell's or one I wrote many years ago.
If you really want to go this way I would suggest getting the proper Bartell's kit, and put that board back in the junk box.
