[ih] What is the origin of the root account?

You left out Ari Ollikainen.  ;-)

Remember it well. (Well reasonably well)  ;-) The XDS-940 was a nice 
machine.  Although, I had not heard the story of its loss.  I am not 
all surprised, knowing the sense of humor around that group.

BTW, does anyone have one of those early one page teletype printed 
ARPANET maps that NMC created?  They showed which hosts were up and 
down.  The application that generated the map was on a well known 
socket and was far too popular.  It was terminated once the map 
wouldn't fit on one page.  It probably disappeared by 73 or so.

One of those should be ensconced in one of the collections some place.
