The ICON was the first computer that I used that had a multi-user interface. Teachers were not trained well and "computer security" was not something that had yet seriously entered our language. While programming them for class was interesting, the real fun was trying to get "cool stuff" to work. We learned BASIC and Pascal in class, but we hacked C and wrote interesting shell scripts after our code worked. Kind of cool to see where it ended up (with BBY and all).

Are there any working examples still out there?
