It sounds to me as if you're doing everything right. You're just not
getting the output on the console you should be. This has me wondering a
few things.

Did you get everything as a whole or is this something you're trying to put
together from a variety of sources? If you did get this as a whole, is it
put together in the same manner it was when this was a working
configuration. Do you have all the packs mounted that were normally
mounted when it was in a working condition.

What version of RSX-11M? Do you know the actual state of your disk pack?

Do you have a terminal besides the LA120? Do you have Serial lines besides
the one the LA120 is on?

Do you have hardware documentation on the 11/34?

Now for anyone reading this, can the 11/34 do something funky like change
the speed of it's console line without having to use hardware jumpers? I
don't think it can, but from the fact that all that's being printed out,
that's my first thought, however, the fact everything looks to work before
trying to boot RSX this doesn't look to be the problem.
