   How did you manage that?  There should be 2MB on the main
board, and I've never heard of a 10MB add-in board.  4MB,
12MB, and even a third-party 16MB, but not 10MB.  (Mine has
2MB+ 4MB, and the page-faulting is something depressing to
watch.  Anyone with a 12MB card in the free-to-good-home
category is welcome to contribute.)

   True, but wrong CPU.  My data say:

   M7620 = KA650-AA/BA = microVAX III CPU (-AA full license,
                         -BA workstation license), 90nS.
   M7621 = MS650-AA = 8MB RAM for KA650
   M7622 = MS650-BA = 16MB RAM for KA650

   M7606-AA = KA630-AA = microVAX II with 1-Mbyte, [...]

   M7607-AA = MS630-AA = 1-Mbyte RAM for microVAX II
   M7608-AA = MS630-BA = 2-Mbyte RAM for microVAX II
   M7608-BA = MS630-BB = 4-Mbyte RAM for microVAX II
   M7609-AA = MS630-CA = 8-Mbyte RAM for microVAX II

   I may have one of those 1MB boards hidden away in the
museum.  So cute.
