La via migliore per digitalizzare questa loco qual'è

Ciao , l'anno scorso comprai la versione America Spectrum e questo è il foglio delle istruzioni...molto scarno , ma almeno c'è il circuito stampato con le connessioni.....
Io ancora non l'ho digitalizzata , quindi ti chiedo gentilmente se e quando l'avrai fatto tu potresti inserire le foto del lavoro...
Grazie ciao Andrea

Se non ricordo male (meglio verificare con un tester), togliere i i cavallotti di rame, dove sono segnati i numeri 1-8.

Saldare i fili del decoder nella sequenza:
1 arancione
2 giallo
3 -
4 nero
5 grigio
6 bianco
7 blu
8 rosso

(Altro non e' che una versione fantasiosa del connettore 8 poli)

Saluti

Io ho trovato quanto segue in giro:

The Bachman Spectrum Series is still having problems with those
pain in locomotive circuit boards being professed to be DCC Ready. To
date, I have been required to remove these boards from their 2-8-0, 4-
6-0, 3 truck Shay, 4-8-2 and NW-J5 4-8-4 engines to fully operate as
DCC. After giving this company the benefit of Doubt, I again tried to
install a DCC decoder in the last engine I bought. Below is the letter
and check I am now sending to Digitrax to correct another Bachmann
design Flaw. Here is the Picture of the Flawed Part?
The Digitrax DN-121 in question was being used in a Bachman
Spectrum GE-44 Ton Locomotive. This was one of their new units that
are reportedly DCC ready. When after about a week of running
(Combined time) it started acting strange. The combined units (DN-
121 & Loco) started running Jerky, both in forward & reverse. After
cleaning wheels and track the setup continued running in this jerky
mode. I changed over to analog mode and the unit would run only in
reverse, and no lights. Removed the DN-121 and tried testing the DN-
121 using my test box, which has no wheels or Chassis s to short out.
Same results, the decoder would only run in reverse mode and didn’t
respond to program changes. Opened the Red/Orange cover and see
no indications of burnt. Leaving the shell off the engine (Spectrum GE-
44 ton) I wired in a New DH-123 to Bachman’s DCC ready board and
it to started running Jerky, only now as it would run forward the lights
would blink on & off as the loco made the short distance on my
program track (32“). I took the DCC board out and checked all points
in the Chassis and motor, for grounds or shorts using a Fluke Meter.
None found. I then tested the Bachman DCC Board using a spare
Ahearn motor and Power pack, which is when I found the Shorting
problem. By Chance or Coincident the two Wire Wrapped Resistors/
components will touch each other when the decoder is installed and
closed within the shell causing a short between the resistors and DCC
connection soldier points.

da quel che mi sembra di capire tra le righe è meglio buttare la scheda e arrangiarsi.
Ho capito male

Ciao a tutti, ho sul tavolo una di queste locomotive (precisamente l'articolo L104407 ILVA Taranto) e vorrei digitalizzarla, qualcuno che l'ha gi
