My 2nd KSR kit looks like the case has original wiring. Here is a photo of rhe LESU. All I am asking is for someone to point me to the wiring diagram, I can probably take it from there.

Thanks for all the suggestions on slots 28 and 29. But I believe Jerry Murphy had it right - Motor Control.

The H key has "STOP" above the "H" But there is no BLANK key on the ASR Keyboard. As I said before, typing FIGS-BLANK-H on another machine caused the function pawl at 29 to operate the switch.
