Motherboard replacement - useful or waste of time and $$?

Talking to Tim at Ring yesterday he mentioned they are developing their own "keep alive" that he feels will be better than what is out there now, no timetable.  I have a k-4 on order to try this out.

I’m still pretty new to this hobby but is there any disadvantages to hard wiring the LM3S to the loco and getting rid of the motherboard. Besides the time and having to add a resistor for each light

Nope. In fact hardwiring is the best choice  for reliability generally.

TCS makes 9 PIN to 21 Pin adaptors.

Yes, but they do not connect on all the needed circuits, as is, to leverage the KA in the board. A full 21pin connection is required. I've been discussing this with TCS for a while now. When TCS releases a full breakout board then this will be a piece of cake. Then we can build a harness with the 6 and 9 pin connectors on it already.
