if you remove these wires and connect them to your printer port (for sfety sake connect via opto isolators) they should drive the lathe.
Many circuits are available online for pc parallel port connection via opto's

Hello I wonder if you can help me the board you quote is this the board that connects to 1 Meg bus cable that came fromm the BBC Plug which on the board refers as plug PL3 which then goes down to the drive control board if so would it be possible to give me a ring on 0115 9389014 (Nottingham) as it might help to have a talk about it to make sure, also I have a complete spare processor board and control board if this is any help.
Cheers for now Colin.
