If I understand correctly....5.5 is the beginning of Legacy and used in early Legacy engines. It can only be used in Legacy engines?
There are 2 chips on most boards. What does each chip do?
Thanks
Dave

RailSounds 5.5 is a 9-bit system for Legacy. As John mentioned above, you may get some sporadic function with a 5.5 board in the TMCC environment (and maybe conventional too), but basically, it's dedicated to Legacy.

The large PIC chip is the microprocessor that contains the instructions/code for operation. The smaller ROM chip holds the sound snippets.

Thank You John
So if one suspected a problem with the sound chip, it seems you have to buy the entire board?
I've looked on Lionel's site and I could not find just the chips. Maybe I was not looking in the right place?
Dave

The chips are usually good or bad, very rarely are they "problematic." What issues are you seeing, which engine are we talking about, and what are the labels on each chip?
