I had laying around. Might have burned out one of the triac for the coil couplers, based upon something Gunrunnerjohn said about resistance of MTH coil couplers.

Yep, if you use the PS2/3 couplers on a TMCC board, they draw far too much current. They'll work a few times before they cook the coupler triac. FWIW, the PS/1 couplers are compatible with TMCC boards.
