  I had always assumed the memory was different - based on the VAX 
hardware reference pages on www.netbsd.org.

  That gives the memory part numbers for the 4000/60 as:
Min 8MB, Max 104MB, installed in pairs, MS44L-AA 4 MB parity, MS44-DA 32 MB 
parity

  And for the 4000/90A as:
MS44L-BC 16MB parity, MS44-DC 64 MB parity

  The memory information for the 4000/90 and 4000/96 didn't have any part 
numbers, but should be the same as the 4000/90A.

  If I get a chance, I'll try some 4000/60 memory in either the 4000/90 or 
4000/90A and see if it works.
