We have an old cnc mill (Novakon 200) that has an integrated computer (no stand alone box), but it is 20+ years old and is giving problems. We would like to buy a new computer and run LinuxCNC on it instead of fight the old box, which was using Mach3. I would like to find a computer with LPT ports on it, or one that could take LPT cards so that we can simply plug the existing inputs from the mill into the machine (yes, I know it will have to be configured). I'm having trouble finding machines that use those, even at places like Tigerdirect and Newegg. I'm not sure if I'm looking at the wrong things. I'd appreciate any help! Thanks!
