Yo,

Actually the JUMPERS are for linking the left and right halves of a
single bus board, not for the top and bottom of a G6. However,
there are posts there for that purpose as well.

Text from link above:

"If you use the A-190 MIDI-/CV-Interface in your system, when you
press a key on your MIDI keyboard, the gate and CV1 signals from the
A-190 will be sent via the INT.GATE and INT.CV to all modules on the
bus. The INT.GATE and INT.CV signal busses can be split into two
equal halves by removing jumpers J1 and J2 (see Fig. 3), so that for
each whole bus, you can have two separate CV/GATE subsystems.
If on the other hand you'd like to have the same internal CV and
gate available on two busses at once, you need to link the two
together, with the special CV/gate leads, the A-100 BC."

Cheers,
