I made a test fixture to test all the modular boards, TMCC and early Legacy. I use it a lot. For folks without such a tool or similar, do what I used to do. Poke the suspect board into a TMCC engine and program it and see if it works.
It's a PIC16F648A, In stock at Mouser. Also, Microchip Direct has them as well.
The R2LC-04 I looked at has the PIC16F84-04, it was obviously a fairly old one. That one is also in stock at Mouser.
Wasn’t the issue with these the availability of surface Mount . Or was the the radio receiver - I remember ordering a couple of hundred of something from china.
