Need Help Identifying Train America Studios Board

I think some clearer pictures of the board without the three Lionel boards attached would help us.  Also, any nomenclature on the board with be helpful as well.

If this is a TAS board, it might be one that was made for a specific model, they had some special for stuff like Atlas switchers, etc.  From all the connectors on the projection at the end, that appears likely that's what you have.

GRJ,

I found this pic from another post on the forum. It was advertised as a TAS board without any additional info. This is the same board except the voltage rectifier is tethered on mine.

There aren’t any screen printed part numbers anywhere on the board. The sockets are labeled which is helpful but not totally conclusive. I’m guessing they used it in diesel and steam applications. I used a steam RS board and set programming accordingly. It chuffs without an external cherry/micro switch and all of the functions work as designed. There’s a “chuff in” socket adjacent to the antenna plug. I’m not quite sure how this socket is used. Also, I still need to find a tach reader board to use this set up on an upcoming conversion.

I never ran across that board in my travels, the guy that knows what it is is Mike Reagan, (Mikado), he used to be TAS.

An early SAW board, Sunset, Atlas, Weaver.  SAW Gen 2 boards were marked. All the small white plugs, left end of the board, would indicate a fair amount of ginger bread lighting functions, and electro-couplers, another reason it could have been A SAW board.  Problem was the board was designed a bit light. Later EOB board beefed-up the basic circuits.   IMO  Mike CT  Usually the (3) component  boards would work on other modular mother boards,  There were exceptions, R2LC pre-08  

Thanks guys! What are the chances that someone has a wiring diagram out there? The sockets on the board are labeled but I’d like to get my hands on one just to have in my files.

Here is the wiring diagram for the board shown above, along with a few pictures of the board and respective connections:

Board Top:

Board Bottom:

Top Connection Detail:

Top row: EOB sensor (3 pin)

Second Row L-R: Smoke Input (2 pin), Rear Coupler (2 pin), Front Coupler (2 pin), Program/Run switch (2 pin; closer to capacitor), Antenna (2 pin; directly below run/program switch)

Third row: Cruise on/off (2 pin), Chuff switch (2 pin; steam engines only)

Bottom Row: Rear headlight (2 pin), Front Headlight (2 pin)

Bottom Connections:

Top Row: Battery (2 pin), Speaker (2 pin), Volume potentiometer (3 pin)

Bottom Row: Railsounds on/off (2 pin), Board AC Input(?) (2 pin), Motor (2 pin)

Hope this helps!
