ROM card question

[shack@crash.cts.com (Randy Shackelford)]

As many of you are aware, I've been working to put an original Apple ][
together. I got the (hopefully) last part today, an Apple ROM card with
integer BASIC chips on it. So I promptly pulled off the chips and the 
Applesoft ROMs off the logic board and put integer on the board and Applesoft
on the ROM card. Everything works but I noticed that the cursor won't move
in ESC mode with I,J,K, and M in Applesoft. This worked when Applesoft was
on the logic board. I deduced that the ROM card works in such a way that the
F8 ROM on the logic board is active even when the BASIC on the card is active.
To test this I put another F8 ROM from an Applesoft chip set on the logic 
board. Then ESC I,J,K, and M worked in int BASIC as well as in Applesoft.
Then I noticed one of those places on the ROM card where there are two half
circles where you can put a lump of solder to make a connection. This spot
on the card is labeled F8. So my question is - if I make the connection, will
the F8 on the ROM card work instead of using the one on the logic board? This
is my prediction and seems like the only logical purpose for this connection.
Does anyone know for sure?
