Hi Ralph, I have thought about that before also. But as Jeff says it really isn't practical.
Have you considered running multiple MiniITX boards in a common chassis and then networking the boards together? Using Modbus TCP which is part of Classic Ladder to interlock the motion between stations might work well. The PC hardware is so cheap that I think it really comes down to space and practicality. I put EMC2 on an industrial cartoner last year that packs bottles into cardboard boxes, and it has been running since last July of 2010, 1-2 shifts per day. The system runs headless and is very reliable.
