Batboard

I'm trying to figure out what exactly the function of jumpers 1B1, 3A3 and 3B3 are. The Batboard Minitor page is missing info for these. Anyone have a clue, or a service manual they can reference?

According to my manual, those jumpers are all out for default settings.
For each the chart shows nothing in the "function affected" column.
1B1 affects function switch S301B-1
3A3 affects function switch S301A-3
3B3 affects function switch S301B-3

On the print it just shows that these jumpers can be used to tie different parts of the 2 halves of the function switch together. I cant see any reason to do so, and they dont seem to have any real use.

It looks like one of those possible "future expansion" things

Thanks BJ, I appreciate you double checking that for me. I might experiment with an old decoder board I have laying around, see what I come up with. I'll post in this thread if I figure anything out.
