Those of us late to the party may like to know:
1. What was AL
2. Why was it famous?
Not AL, but AI. Also known as MIT-AI on the ARPANET. It was the PDP-10
used by the MIT AI lab, hence the name. The Incompatible Timesharing
System was developed on their PDP-6, later moved to the PDP-10. There
were three more ITS machines in the 70s: MIT-DMS/Dynamic Modeling,
MIT-ML/Mathlab, and MIT-MC/Macsyma Consortium.
If ITS doesn't ring a bell, maybe some of its applications/tools might:
Maclisp, Scheme, Logo, CLU, DDT/HACTRN, SHRLDU, MacHack VI, Macsyma,
Maze(war), Emacs, Zork.
3. Tell us more about Doug, and his apartment :-)
I'll leave it to others to talk about Digex.
