No issue with the LinuxCNC recommendation but I think Super Tech can provide a Mach3 configuration with the parallel port pinout already considered.
If they start trying to mess around with parallel port details they will get into the weeds with: ECP/EPP/SPP and DMA/interrupt assignments as well depending on the configuration of their PC.
