Well in the Disco II (yes the later models...) the remote is via a
resistor chain and switches to connect each join between each resistor
to another wire so not quite what you are describing but pretty
similar.
Been digging in the RAVE and this is the remote switching for all
variants in the Disci II (fixed pitch font required):
<---+---390R---+---470R---+---820R---+---1E3---+---1E3---+
To | | | | | |
Radio s V+ s V- s S+ s S- s Mode s Remote
| | | | | | end/End
<---+----------+----------+----------+---------+---------+
Where:
s is a push to make switch
V is volume
S is skip
I'm not sure what value the 1E3 represents it could be 1.3k ohms or
1.0k ohms. As can be seen if the resistance of the V+ button is 860R
(ish) it is the same as the S+ button.
Of course there is no telling of the Disco I arrangement of button
fuction and/or resistor values is the same but a merry few minutes
with a multimeter should see what is going on.
