I am surprised how long the LPT port has lasted. Many of the new Intel Bay Trail boards either have LPT ports or a header on the motherboard. Apparently the LPT port must be used by a lot of embedded systems. Otherwise why would they continue to include that?
It seems like the PCI slot is endangered. Some of the newer boards are slotless. The cost of a spare motherboard seems slight to me considering the overall cost to implement a CNC system. IMO, if uptime is critical, put spare parts on the shelf and that solves the future availability issue for the most part.
