Unfortunately not. I removed all the expansion cards, but it still complains about memory. It has a daughter card mounted on the main board (not in the expansion slots). The 350 has two cards that appear to be physically the same (connector wise), but different part numbers and different chips (I have not looked up their datasheets). It would be nice to try the 350 daughter cards in the 380, or vice versa, as neither machine works, but at the moment I don't really know why. Regards Rob
