I was just reading SERVO, and a guy is using one of the PicoITX boards. Low power consumption, small, and could do well, but I would like a board with 3 or 4 parallel ports available, even using a 'plug in board'. That would give all the expansion I could ever think of. But building a parallel port board can't be that big a deal.
I don't know what happened to the real time projects. I suspect that many of them migrated to doing embedded systems, or virtuilization. Unless someone has a real need for hard real time (like machine control, etc) using an attached embedded system may be easier and cheaper (given the time cost in the software). But that is just my guess. As computers get faster, and if lightly run response time shrinks, near real time might be good enough for non-supercritical projects.
