Yeah, that should be a 4Meg board.  So including the 1Meg on the CPU
board, you'd have 5Meg of RAM.  That's a pretty tight config for
NetBSD/vax but it'll certainly run. :-)  If you get things running, you'll
certainly want a streamlined kernel.

You're in luck here.  I don't know how I'd ever get along without network
connectivity.

That's a shame.  How are you going to setup your own VAX terminal
room without a MUX? ... I can maybe help out here.

I'd definitely try to get your hands on the one in the Physics dept.  It
never hurts to have more options for troubleshooting.  Depending on the
red tape involved with acquiring the dead system from the Physics dept,
you might to clandestinely swap power supplies between them.  I mean, if
its already dead, what's the harm in making it twice as dead?

Just move them over into the 5 slot... or get a MUX module and fill in the
gap. :-)

You've at least got a DEQNA though, so you can bootstrap your system
install from the network if you're motivated to setup a bootserver.  Did
the system come with any hard drives?  Ideally you'd want an RD54 (160Meg), 
but you could get by with a smaller drive and some NFS mounted filesystems.
