I have a question for the folks here on this thread... I am toying with a DCC decoder (derived from a design I created 8 years ago!) as a swap for our TMCC radio board. If successful, a one board swap out without any wiring changes would allow DCC support with our current motor, smoke, and light controller; and also link to the RailSounds system. Would folks be willing to purchase the "DCC adapter" to plug and play upgrade locos such as the SD-70, Y3, U33? Figure costs at $50/board for evaluation of the concept. No promises, just exploratory feedback - as I may run into some technical issues in the current board set that prevent this concept from working out...
That's a very exciting prospect!
