SSC DTE/DCE "Jumper" Pinout ?

[Zero dB <no@email.com>]

Greetings All, 

Sorry to trouble you with this, but I've received a genuine apple SSC
to use in my ][e machine, but it came without the 8-row jumper with
the triangle printed on it to select "MODEM" or "TERMINAL" on the
board!

 I've had no luck finding out what's going on inside this "selector"
board, and was wondering if someone could give me a definitive
schematic for the terminal selector block that is used on the SSC, and
how it's relative to the arrow's position ?

Guess I'll need to just use some breadboard jumpers to make the proper
closures... just need to know which to close. Will be using both modes
at different times. 

Thank you so much!  I am steamed that the jumper block was not
included!! grr :)

Thanks again.
