The 380 has memory on the motherboard, and a model-specific
daughtercard for expansion memory.
It seems reasonable that the Pro bus (I/O card) expansion memory should
work in both models, but I don't have any to try that.
If you have a 380 complaining about memory and it has a Pro bus memory
card installed, I'd suggest removing that card to see if it's happy with
stock motherboard memory.

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.
