Some interesting stuff in here.

On page 4, a note from Raj Reddy about a tape drive not working correctly. Reddy was an assistant professor at Stanford at the time (1967). He went on to win the Turing Award in 1994 for his work in AI. (https://en.wikipedia.org/wiki/Raj_Reddy)

But apparently he had time to play computer games. On page 15: "SPACE WAR BUTTONS DO NOT WORK. - Pingle and Reddy".

On page 1: "TTY 3 threw its drive belt". Anyone else here remember the days when terminals had drive belts? (On page 6, some output from one of their printing terminals pasted in.)

On page 10: "MY HARDWARE WORKS!". Looks like they were building custom hardware and hooking it up to this machine.

Here's the Wikipedia page for the PDP-6, complete with a photo: https://en.wikipedia.org/wiki/PDP-6

Yeah...ASR-33s. But TTYs are just character devices and could be other things that had belts.
