Help! AT&T 3B2-310 Docs and Unix rev.

[Wise men still seek Him]

I am in search of documentation for an AT&T 3B2-310.  The hardware reference
would be especially helpful.  Also the docs for C.

Any UNIX wizards (ala AT&T) that know the current revision of the operating
system that will run (correctly) on a 3B2-310?

Any answers would be greatly appreciated.
