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.
