This installation of TCS M1 Decoder is for HO Scale ROCO BR 112 and was performed by Vilas Shukre of  Selangor Malaysia.

Important Soldering Tip:
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157

I  installed M1 decoder in an old version of Roco locomotive Type BR 112 of German railways. I adjusted the dither to suit the locomotive and the result is great.

"The installation requires knowledge of soldering and some mechanical aptitude. But it is manageable with a little patience. I have changed the bulbs to 14V  thereby eliminating the need for resisters.

Basically it is a two step installation - 1. Modify the on-board PCB as shown. 2- Solder the decoder wires according to TCS manual."

Other solder tips: When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
