  Well it was my first computing experience, so I'm
pretty sure it was a
 3000.  But given two old timers from my first computing group both
 said it was a 2000, now I'm on a hunt for documents that will say
 definitively :-).  Until then its my memory vs. their memory. 
You had to type something to log in, right?  How'd it start?
  "HEL-" (2000)
  "HELLO-" (2000)
  "HELLO " (3000)
  I remember that on the HP we all used a
"demo" account.  I can't
 remember if the accounts on the HP were numeric or alphanumeric. 
HP2000 would be a letter followed by three digits, e.g. H999.
HP3000 would be (at minimum) two labels, "user" and "account", of one
to eight characters each separated by a period.  Could also have a
"session name" label in front followed by a comma, and/or a "group"
label at the end prefixed by a comma.)  First character of each label
would be alphabetic, second and later characters alphanumeric.
