It used to be that when someone took the ITS system down, to use the PDP-6 in stand-alone mode, it would automatically load the music player and play the Star-Spangled Banner (executable file @ BANANA) to signify that time sharing was signing off.

I talked to @gjs some weeks ago, and he said he'd have the printout scanned.
