The equivelant in VMS is sys$crmpsc.  I can supply a sample program
(in macro32) which calls it to read the firmware in a VAXStation 2000.
I don't know the right addresses to use for an Alphastation 200 though.

(Congratulations on the progress made so far.  Maybe there is hope yet
for my two DEC 3000/600 machines which have similar symptoms.)
