Hi Dave Perhaps you missed my point. All of the EMC was running on headless linux boxes. The Mac was the display point for the interfaces to these boxes. No need to build a custom kernel or a custom ethernet board. Both the headless Linux/rtai/emc boxes and the Mac had ethernet ready to do what the NML stuff requires.
With some of the "Modern" GUI interfaces this poses a problem because they insist on direct to HAL communication.
