Hello everyone! Me and my friend recently got permission from our shop teacher to resurrect a old Lab-Volt 5600 Milling Machine at our High School and need some advise/help. Our predicament is the following: We need a Software key that connects to the parallel port (printer) on our milling computer to allow the Lab-Volt Level 4 Milling Software to work, and we need to know if we need any special hardware (other than a serial port) as the original computer has a motherboard BIOS password that nobody knows. If anyone can give us some knowledge that would benefit us immensely.
