John,

The 2550 is a neat little minicomputer. I have one but, it has a bad
processor card so, I've never actually got it to boot. Sooner or later,
I'll find a replacement card for it.

IIRC, I was able to connect a dumb terminal to the console port at 2400
baud. I was able to talk to the diagnostics processor and run the startup
sequence at this speed. There's probably a configuration setting for this
but, I don't know what it is.

I have a fairly complete set of DOCs for the machine (as a matter of fact,
most of them are still in the shrink wrap). I'll be happy to share them if
you are missing any volumes. If you have any specific questions, I'll try
to look them up for you.

The "2550 Operators Manual" will probably be the most useful at this point.
It has the basic system operation and getting started guide. Do you have
this DOC?
