Its the 'mbus' that is inside the CPU box. On the VAX 4000/300 thru 
4000/705a the CPU has a separate backplane to memory (replaces the top 
connectors on earlier models) that was faster and wider. Thus on these 
machine the CPU sits in its slot and memory sits to the _right_ of that, 
then all of the slots to the left of the CPU are Q-bus. While I've got my 
collection temporarily at home I need to get some pictures of this up for 
my web page.
