Hello,
Can anyone recommend a good X58/LGA1366 motherboard that has a parallel interface? In looking at mobos for a new build (i7) I am hard-pressed to find any that do.
Your best option is to purchase the Gigabyte GA-X58A-UD3R motherboard and a PCI adapter for your parallel device. I'm not aware of an X58 board that supports one on the I/O panel.
