It varies. The first thing the processor does is retrieve data from memory and the chip. The software or firmware can vary and when it replaces memory from the chip it may make the top board non operational.

Since the software QSI made overtime evolved along with product some are not compatible. MTH required certain capability and excluded others that QSI was working on and installing in their systems. All soon over run by Lionel TMCC and then MTH DCS.

Josey, That C3 top board may be your issue. That probably only work with the very early 1993/4 Chip like the basic F-3.
