The Honeywell 516 was the basis for the ARPANET IMP, which later became 
the ARPANET TIP (on a 316 by then.)  The IMP was the router that held 
the ARPANET together, the TIP an enhanced version that allowed terminals 
to telnet to hosts on the net.  This version of the 516 didn't run 
anything like UNIX.

Is it possible he got access via the ARPANET?  Or that somehow his 
access got confused with the ARPANET?
