We in Russia started using PDP-11 when you guys were almost dome with them and even VAXes were on their way out.
So I had my fun with them, repairing (yes, troubleshooting down to a component - no luxury of swapping and tossing boards; sometimes even tracing the microcode and replacing ROM) for which I had to write short assembly programs or even in codes directly right from the key switch panel.

Means "set the interrupt bit 6 in the Console Display's Keyboard Command Register".

means "display on the console's screen what you've just typed on the keyboard".
Fun
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
