Part of the iconic mainframe experience is the cold room sounds; for early
Multics installations (and other systems) the sound of the Selectric
operator's console.
I/O Selectrics are rare, expensive and unreliable.
If some good quality audio clips of a Selectric were available, it should
be possible to jimmy up the console terminal emulator to make the sounds.
So I am fishing for any existing audio clips with clean sounds, or someone
with a Selectric that is willing to make some recordings, or a pointer to
somewhere where all of this has been done already.
