Hi James,
On my Q219s, the lower 10 way (S0) are the LP signals, and the upper (S1) is the video.
This is confirmed by the IIx service manual, both in the schematic, and in the theory of operation pages for Q219 page 41.
S0-pin4 is 5V for the lightpen, presumably, but the cable doesn't seem to carry it.
S0-pin2 is LPHIT-bar
S0-pin5 is LPTOUCH-bar
S0-pin7 and S1-pin7 are composite video out.
S1-pin8 is earth for the video.
S0-pins 1,3,6,8,9,10 are earth
On the series III the 10 way carries only video to the back panel, thence out to the vdu.
But if you're just looking for video, looks like either connector would work as long as composite and earth are the only connections.
But to suss out the VDU, you can simply inject normal composite video into the relevant lines plus earth. You don't strictly need a CMI, but you'll need the AC power for the Series III vdu.
Get hold of the service manual for the series III and verify the power connections on the cannon (amphenol?) connector that goes to the vdu. The PSU lights on the SIII have a label for VDU power to help you.
Lemme know how you go...
Cheers,
Joe

Hi,
I am trying to get my original CMI series 3 vdu display unit to work. There are two 10 pin male amphenol connectors on the front of the Q-219 mono graphics card. Which one do I plug the 10 pin female connector into , the top or the bottom one on the card ? This 10 pin female then takes power from the Q-219 card to the rear of the CMI which then supplies 16V AC power to the vdu. Thanks .
