Hi again.
Just had a look at the circuit diagram.
Here are the pinouts on the microprocessor board
1 ov
4 analog out (motor spped control 0.1 - 8volts)
5 forward spindle
6 reverse spindle
7 X Direction
8 X clock
9 Z Direction
10 Z Clock
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
good luck Ray
