Yes, you can add 4 1MB SIMMs to your SE/30 to get a total of 5MB.  Only catch
is that you'll have to relocate the 256K SIMMs from bank A to bank B and put
the 1MB SIMMs in bank a.  This works like a charm.

This is the same solution as for a Macintosh II, Macintosh IIx, and Macintosh
IIcx, except that there's less room inside so you can't use most DIP (read
over-size) SIMMs.  Stick with SOJ.  (Yes, this means that you can't use our
own 4MB upgrade in the SE/30 since it uses DIP SIMMs.  You have to use two
of our 2MB upgrades, which use SOJ chips, or a third party SOJ based solution.)
When you buy, just ask for SIMMs that use low-profile or SOJ RAM.
