I got a bit more work done today. The side panel was removed from the machine and fitted with the new mobo, ICM 2900 (breakout board for Galil board) and places for two 50-pin ribbon cable breakout boards (made by Phoenix Contact). I made a angled bracket from some 1/16" x 1" aluminum angle that mounts to the rear of the motherboard tray (and cut couple tabs out of the scrap) to mount the motherboard to the side panel. It worked out pretty good allowing the motherboard to be removed with four thumb screws (the former case screws). I had to remove the wire duct shown on the right of the side panel as it was way to tight in the corner. The 64 point I/O extension from Galil uses two 50-pin ribbon cable connectors, so I'm running a ribbon cable from the Galil I/O board to the Phoenix Contact breakout board. I can then run separate cables up to the two 16-point Opto-22 racks. I still have a spare 32 I/O points ans the place to mount another breakout board, just no place to mount anything else .
