[07] HOW MANY USERS HAVE BEEN LOGGED IN AT ONCE?

     Try 'maxusers' (-h for options).  We only started keeping
     track of maximum concurrent user counts in 2001.  But we have
     archived wtmp logs going back as far as 1993:

       1 users in 1987 (1  telephone) 
       4 users in 1991 (4  telephone + console)
      10 users in 1993 (10 telephone (later slip)
      25 users in 1994 (10 telephone + slip)
      50 users in 1995 (4  telephone + isdn)
     100 users in 1996 (4  telephone + dsl)
     125 users in 1997 (2  telephone + dsl)
     150 users in 1999 (2  telephone + dsl)
     200 users in 2001 (dsl only)
     250 users in 2002 (ds3 only)
     300 users in 2003 (ds3 only)
