Ouch!  I knew there was something I was forgetting.  That's what the 
remaining slot would have to be filled with, a RAM board.  Is the 
MXV11-B only dual-height?  I thought all boards like that are 
quad-height, but then I don't own any.

I discounted the Falcon and the like, as I prefer a faster system.
