  VAXstation 4000 model 90 memory? 
 The Question is:
 
Looking for Memory configurations for a VAX4000/90
 
 The Answer is :
 
  Please do not abbreviate system names.  In many cases, very different
  systems will have very similar names.
 
  The OpenVMS Wizard has never heard of a "VAX4000/90", but will assume
  you are referencing the VAXstation 4000 Model 90 system.  (The VAX
  4000 series is quite different from the VAXstation 4000 series, as
  an example of the above.)
 
  Memory must be installed in this particular VAXstation system in sets
  (banks) of four matching SIMMs.  There are 8 SIMM slots total, so one
  or two sets of SIMMs -- one or two banks -- can be installed.  Banks
  that are partially populated are not permissible.
 
  The SIMM slots are labeled (in order):
 
       0A, 1E, 0C, 1G, 1F, 0B, 1H, 0D
 
  where slot 0D is closest to the front of the system.
 
  Fill slots 0A, 0C, OB, and OD with one set of SIMMs; with one bank.
  Fill slots 1E, 1G, 1F, and 1H with the SIMMs of the other memory bank.
 
  Supported memory sets are 16 MB (4 x 4MB SIMMs, order number MS44-AA)
  and 64 MB (4 x 16MB SIMMs, order number MS44-CA).  Compatible
  third-party memory may or may not be available.  The mixing 70ns and
  80ns memory SIMMs within the banks of this system is NOT recommended;
  use only one speed for all memory SIMMs installed in this system.
