      work but I'll need someone with more expertise to confirm that.

      -Turn on, WAIT light should be on
      Enter C3 00 00 program (Jump 0000)
      -Turn 16 Address switches off
      -Flip Examine switch UP
      -Set Data switches to C3
      -Flip Deposit switch UP
      -Set Data all off (00)
      -Flip Deposit switch down twice
      Verify program entered
      -Turn 16 Address switches off (should be from last step)
      -Flip Examine switch UP (Data should display C3)
      -Flip Examine switch Down twice (Data should display 00 twice)
      -Flip Reset Up
      -Flip RUN up, address and data lights blinking fast and faintly

      I made some new schematics for the IMSAI, redrawn to focus on operation and in colour.

      Congrats on your great find!
