Mac SE FPD board connector

[iPhil64]

Hi all !

I just acquired a Full Page Display board for Mac SE, which is good, because I do own an FPD

However, the board was sold with just the ribbon cable from the card, and I guess there was something to connect it to a bracket leading outside.
Do we have the pinout for this ?

I have an SE/30 Full Page Display board that i haven't gotten to work yet, but it did come with the external connector bracket. Does you ribbon cable and connector look like this?

Let me see if i can trace the wires...

Here's what i was able to trace out.

External Pin (facing connector)	Color	Internal Pin (from top of card)
5	Orange	2
4	Red	4
3	Black	5
1	Clear (bundled with Black)	8
2	Black (bundled with Clear)	9

I'm not sure what the functions of each pin are. I can guess that the clear and black bundled wires are the actual video signal. Red and Black being 5v and GND. And orange a sense?

@iPhil64 on your monitor connector, are there any pins on the connector that are tied together?

Thank you !
Interesting, I have a totally different card from another vendor in fact ! See attached pictures.
And I found someone with a similar card (DPD instead of FPD, I guess for Dual Page Display ?) on 68kMLA forum (see https://68kmla.org/bb/index.php?threads/lapis-technologies-se-dpd-video-card-info.3112/) so I asked for identifying the pinout.

Oh good point, I should check the monitor as well.. it's just currently buried behind other Macs.
