Anyone have the pinout/connector type of the duo's internal modem port?

I got some "plans" for this port.

Is something like this what you're looking for?

page 58 of: http://homepage.mac.com/micahgartman/web/sahnapiranha/dev/dn_duo_system.pdf

The modem card connects to the computer’s main logic board through a 50-pin, dual, in-line socket JAE connector, part number SX20-50P-LTS-MH2-2T which plugs directly into the connector on the edge of the main logic board

It also has a list of all the pins and their functions

Great Find!

I can't even estimate how many times I've been through the Duo DevNotes. :I

I didn't remember that particular info was in there because my ONLY interest in that slow-poke POS MoDem was to remove the pitiful thing and hack something useful in there.

By the time I started hacking Duos, I'd long since moved on to a 56k External FAX ModDem that was Duo Styled in Color & Form!

I seen that doc already. Thats what prompted me to post this thread.

It tells you the power connections and etc. but NO data connections. data connections are important.
