Is the circuit board that comes in this tender a DCC board?  If so is there a diagram for the six pin connector?

Thanks, most of the stuff I have was purchased in the 60's, I just recently got interested in returning to Model Railroading.  The passenger cars I have are Atlas silver AT&SF with Rapido couplers.  I also have a brand new pre-Spectrum B unit (Bachmann +)( reviews say they are not reliable) with Rapido couplers.  I still would like to know how to change the couplers on what I have.  How do I get the factory rep to address my question?

I have two sets of F-7's, one set has Micro-Train couplers installed. and the coupler box has a small plastic plate with two clips that catch on the coupler box.  The other set has dummy knuckle couplers, and a plasic bag with 4 NMRA style couplers/springs.  The coupler box appears to be different, the top plate attaches differently to hold everything together.  I can't readily figure out how to dissassemble the second set.  I wanted to run the engines F7-A-B-B-A.  Thanks for the help, if you have additional answers send them.

Thanks 

To Bach-Mann:
How do you convert a brand new Spectrum F7 A & B from knuckle couplers to the included NMRA style.  I don't want to damage anything.  Diagram please?

Thanks
