Hello

I have now powred up my "stone age" Terco 45 cnc mill, and all axis are moving as they should when i jog them in manual.
So here is the question: What do i need of software to transfer g-codes an program in genral from my computer to the controll unit for the cnc?
Connection between the cnc and computer are lpt port (25 pin).
I have no manual etc for this machine
