Re: University credentials used by third parties

[David Gillett <gillettdavid () FHDA EDU>]

   The Computer History Museum has a 1620, or perhaps it's a 1710 (enhanced
successor).

  Or rather, it has the shell of one.  Somewhere inside the cabinet, a Mac
II is running a simulator program that allows it to execute actual code.  I
could tell there was something fishy about it when I saw the CPU/console
unit but no accompanying freezer-chest-sized memory units....

  Oh, while we're gazing deeply into our rear-view mirrors:

  I first learned to program on a desktop machine -- an Olivetti Programma
101.  It could store about 100 instruction steps on a magnetic card that was
about 4" long by 1.5" wide.  The year was 1969, and I was 12.
  My Dad got his local Olivetti salesman to bring one to our school so I
could demonstrate it to my classmates -- first time I ever had a demo crash
on me in front of a live audience....
