November:
In what is believed to be the earliest example of around-the-world networking, a link is made by operating a PDP-6 in Perth, Australia from Boston via a telex link.
The PDP-6 was operated and programmed from Boston using a 12,000 mile, 5 hole telex code. It proved very difficult to generate a control C in 5 hole code. At one point in the session, Robin Frith in Perth asks Alan Kotok in Massachusetts, "Do you think you could let us poor Aussies have a bit of core?" Pictured is Alan Kotok seated at a PDP-6 while Gordon Bell looks on. |
