This and the fact that there is no supported frame buffers for X actually 
makes the "reality" that no VAX platform is fully supported by NetBSD. Yes, 
its unfortunate.

To dump a "good" copy of the PROM very slowly, you can use the Examine 
command to dump out the contents in HEX to the console. If you do this 
while connected to the console via a serial program or using something like 
the DECServer 700.

The good news is, that with a good copy of the prom you can selectively 
repair the damage. I've snarfed a good copy of my VS4k90a (but my 4k90 PROM 
is already toasted) and unfortunately they aren't similar enough to see any 
meaningful differences.

When the system starts, what banner does it print? The interesting bits are 
does it print the speed of the system in Mhz? and what version of VMB does 
it have?
