A quick view in the manual Anonio sent me provides much of information,
even the memory map of an rtVAX300 System, desription of the VM System
(full featured VAX as it sounds), the Ethernet controller and alt least
a part of the surrounding hardware that's needed to run a minimal system.
Naturally there is no info about the four (?) Altera PLA's that are on the
board, hope I can get some infos about this from the company that made the
board.
I'll do 2 things next:
1. Read out the roms (you will get a binary)
2. I'll compress some of the infos from the manual for you. (..and provide
it here).
..
I'll put up a copy of the manual to my webserver if I get Antonio's
permission.
Good night for now,
Holm

Okay, as you say, there's clearly something there. It's moderately
likely to be where the ROM lives on your machine.
As a first tentative guess, I would start picking this apart assuming
the CPU starts executing it at 2004a531. If you can dump the whole
thing (you might be able to do binary search to figure out how large it
is) someone can probably disassemble it. If you aren't up to
converting it to binary, I could take a big blob of text capture from
something like "e/l/p/n:3fff 20040000" (or whatever n: value gives you
the correct amount for its size) and convert it to a binary file easily
enough. I might even have the time to do some preliminary
investigation, though I can't really promise anything there.
