Install Disks for AT&T 3b2/400

So I've had a 3b2 sitting on a shelf for the past few years. Prior to that, it lived in car trucks and basements, since about November 1993. Presumably, it was never powered on. A couple weekends ago, I ran across it while cleaning and, weighing the risks, connected it to a terminal and powered it on. It booted happily, checked its disks successfully and allowed me to add an unprivileged user account. It's running System V Release 3.1 for the AT&T 3B2, Version 2. Other than the unsurprisingly dead Tadiran clock battery, it's pretty cool. It even has an ethernet board. The one thing I can't do, however, is change the root password because I don't have the install diskettes. From my research, I've seen that a 3b2 without install disks can be considered "down" for all intents and purposes. Can anyone contact me on or off list about getting originals or copies of the install disks? Thanks. Anthony
