I am in the process of obtaining hardware documentation for an AT&T 3B2-300, but am in need of a minor piece of information before I receive it. I need descriptions of the console terminal port pinouts and the terminal port printouts (if they are not the same). This information will permit me to bring up the system and examine what is on it. Thanks in advance for any responses. Jim Smiley
