This is the emulated output on the operator’s console. The green text is typed input, possibly followed by a comment.
Settings of the switch register are show as 3 numbers separate by slashes.
Other typed input does things like mouting mag tapes. Anything containing lower case letters is a comment from the emulator, often about magnetic tape action.
Emulated typewriter output is all upper case and prefixed by a number and T/W:. Only the stuff after the colon appeared on a real Leo III typewriter.

The emulator is a simple command-line program and can be run on a whole variety of machines.
On Windows use the command prompt, and on UNIX-like systems use the standard command line.
