I have the PCB and instructions for a Johannes Hausensteiner kit here; the
instructions mention the following mandatory changes to KLM-367:

 B) On KLM-367:
          - Remove the  backup battery.  There is a  lithium battery on the
            new MIDI pcb you received.
          - Disable mute circuit during tape interface mode:
            - Cut pcb trace to IC5/pin3 directly at IC5/pin3 (solder side).
              Be sure not to damage the passing by pcb trace.
            - Connect IC5/pin3 to IC5/pin7.
          - Connection cable to MIDI pcb:
            - Solder the open ends of the supplied 10 way cable (drawing no
              PS 6M 00 05 004) to the respective  target points on KLM-367.
              Refer to drawing.
