Yah, pretty sure.  I know there are at least 2 people on this list who 
have done this to 345/375s, and I'll let them speak up if they wish ... 

On the 345, you'll need new ROMs (upgrade to the ones in the 380), but 
I'm not sure about the 400-series, since they had some of that weird 
Apollo goo in them...
