Franklin Ace 1200 -odd little jumper

[Ernest <leucoplast@seanet.NOSPAM.com>]

There is a little jumper wire on my Franklin Ace 1200 motherboard, and I
have no idea what it is for. Here is a picture of it:

Does anyone know what this odd little jumper/short is for?

Here is a sketch of where the wires go to, with the chip type listed next to
it:

I don't know what the pin numbers are but...

If you hold the SN74LS20N chip with the notch facing left, the wire connects
to the second pin from the left on the top.

If you hold the SN74LS08N chip with the notch to to left, the wire connects
to the sixth pin from the left on the top.

I'm not sure what these two chips are for, but I've run the computer with
the wire plugged in and out, and I can't see any difference in how the
system performs.

Any guesses as to what this jumper is for?
