You could wire each victimswitch in parallel to a unique keyswitch on a keyboard.
Don't use one of the priceless old ones. Trade someone for 2 of the new ones.
On second thot, sacrifice an old dumb terminal attached to a serial port.
*CAUTION*. I am a software person and have done none of these things.
I do have an old keyboard. I'm keeping it.  ;-)
