Apple Monochrome Portrait and Two-Page Monitor Sync

Afternoon folks.

Does anyone happen to know with certainty if the sync is overlaid on the monochrome signal, or provided on the separate sync pins on the monochrome portrait display and two-page display?

OK, fairly sure it is separate sync or I'm missing too many sync pins :) Unless my monitor is playing up. I made an adapter to reorganise the colours in the cable Slomacuser sent me because they didn't match the pinout for the apple cables and it still doesn't sync. Must be one of the missing sync pins that is the issue.

You're probably aware... but this refers to a cable pinout doc :

...which is no longer available - but thanks to a little archive.org-fu, it's here :

Sounds like the Two-Page uses the same cable as the Portrait display
Yeah, the only cables on ebay in the last year and a half have been on a spotty tablecloth. Slomacuser sent me a cable that didn't work on his portrait and I've been trying a few things to see if I can get it going. I have pinoits etc. I'm just trying to work out what pins are critial and what aren't (just bwcause they're labelled / reserved doesn't mean they're needed!).
