I have an older PS2 Steam Engine, 20-3038-1. It has the 5v board.
I want to experiment with sound files with the newer PS2 3v Tender from a Railking engine 30-4014E-1 from set 30-4104-1.
Both tenders have the same 10 pin tether. Can I just temporarily swap tenders safely while I experiment?
It's my understanding that the sound sets are better for the newer 3V PS3 engines. Is that true?
