Notes:

Don Thompson provided a series of photos of the various PC boards used in this locomotive, mostly as a reference guide.

SHS part #01674 is the infrared sensor flexible printed-circuit board. This is press-fit on one end, so one has to be careful when removing it.

This is the LocoMatic board for the engine, mounted in the tender.

This is the LocoMatic AC/DC sound printed-circuit board (part #01633).

This is the locomotive's DC shorting plug, to be used only for this engine (part #1096-X0). This shorting plug only allowed current to the motor from the rail, and 5 volts to the LED, not the smoke unit or optical detector. The optical detector on driver #1 would allow 4 chuffs per revolution.

This is the locomotive's under-the-cab printed-circuit board used for ribbon cable, motor, headlight, smoke unit, and pick-up (part #1096-X003).

This is the locomotive's socket printed-circuit board (part #1096-X004).

This is the locomotive's DCC interface printed-circuit board (part #1096-X036).

This photo shows the DCC interface printed-circuit board (part #1096-X036) with a QSI Titan DCC sound decoder.

This photo shows the Soundtraxx Tsunami version installed in the tender.

This diagram shows the DCC interface design.
