OK, I'm still a little confused. Do you have Boot ROMs in the system, or
even when it's put together in the 'bootable order', do you still have to
type in the bootstrap?

The bootstrap expects to be seeing the controller at a specific address.
I believe a MSCP disk should be at 1772150 for the first controller (I'm not
at home, so this is from memory, and my memory stinks).

I've typed the TMSCP bootstrap a few to many times for my taste. Though now
I have a board in the system that included TMSCP support. This is the only
reason I'd use a PC as a console.

I'm afraid I don't. My personal recommendation is get a DEC terminal, but
then I've got anywhere from a dislike to downright hatred for non-DEC
terminals.
