  The uVAX-II 
 offered 1meg of ram on card, FPU and a faster memory interface(PMI)
 along with denser 1mb, 2mb, and 4mb (and later 8/16mb) cards.  This made
 a 5mb microvax-II possible in two cards instead of 7 using uVAX-I!  
AFAIK the MicroVAX I can't do 5MB no matter how many cards you have. It's
a pure QBus machine; all memory lives on the QBus and there is no 
scatter/gather map to allow it to get to more memory than the QBus can
address, which is 4MB.
