Yes, BUT I'd just finished doing some Q-bus research and I believe my
problems are somewhat related to my general ignorance of how to organize
the modules I have :-)  After gaining more knowledge (and interpolating
the blank spots), I tried this configuration.

Pretend you've taken your BA123 enclosure and have tilted it on it's face
( I do not recommend actually doing this at work or home ).

For all I know the above configuration will be outrageously humorous to
those in the know. Previously I'd stuffed any the open slot 3 and 4 C-D
sections with double width cards.  I thought I needed to keep all that
free space plugged up.  Apparently the MicroVAX interpreted whatever
combination of cards I had in slots 3 and 4 to be an extra 4Megs of
memory.  In the configuration I've got above, NetBSD correctly detected
5Megs of memory -- but something is still off (either that or I've
discovered a new model of MicroVAX :-)

 realmem = 5241856
 availmem = 3296256
 Using 255 buffers containing 261120 bytes of memory.

How should I be arranging the Q-bus cards?  Am I still missing something?
