There are lists to be found via google. If it's a 3B1 running AT&T System V, then I'm almost positive there were some very popular default accts that had to be removed -- most people didn't and resulted in many machines being vulnerable. Also, don't know anything about the file system, but if it's a common one, you could potentially (and carefully) install the HD into a linux box, mount it, retrieve /etc/passwd, and crack the sucker. With today's machines you might be able to brute-force the keyspace, or worst case, put a pretty good dictionary attack on it. HTH Keith

I'm not sure what specifically differed.... but even from PC to PC, the one or two times I attempted to do it didn't work (different brand/model controllers). I suppose that it the PC MFM controller used the same chip that the AT&T 3B1/UnixPC used you would stand a chance, otherwise, doubtful. Anyone care to confirm/deny ?

Am I smoking crack, or do the "mount it on a PC" answers ignore the fact that it's an RLL drive?
