VAX questions, memory - test-drb@ccmp.vtda.org

 I finally got my hands on a VAX 4000/90 (yipee!) and it
now takes its place 
as my fastest VAX. It has 32MB of memory (8 x 4MB modules) and I was 
wondering if, because it looks a lot like a VAX 4000/60 if I could use 
memory modules from a 4000/60 in the 4000/90. Also since I've only got 4 
16MB modules, can I mix 4MB and 16MB modules?

The memory (MS44) from a 4000/60 will work in a 4000/90 in every case I've
tried.  All the simms in a bank must be the same capacity.  I think there 
should be a diagram of the banks on the inside of the cover, or you can
determine the banks by the etched/silkscreened numbers next to the simm
sockets.

I'm sending this email from a 4000/90a which was quite a step up from my
VS3100/30.

Good luck.
