Who, me? The problem is that I don't have any cable between the card's pin header and an external connector... No, that'd be CelGen. He's got the NuBus Card & Pivot Monitor to try with stock a stock Mac Video Cable . . . I'm guessing, based upon my confirmation that the Non-NuBus Cards appear to use a standard Mac DA-15 Video Connector Pinout . . . that discovery and confirmation was expedited (gave me a kick in the pants to get started on it again) by the SillyScope Data for the Video Lines and their ground shield complements posted by you for the RCPII/IIsi Card . . . for which I have a working cable . . . which leads me to ASSuME that CelGen needs but try a stock, straight thru Mac Video Cable.
There! PARSE THAT!!!!!!!!!!!!!!!!!!!! 😱)
I'll try cutting a (long) female pin header and soldering the cables on the PCB-intended pins :-/ I'll reply to this in: IIsiColorPivotII_PDS_Card_HackProjectâ„¢

Got fired from work. 😛
Well, now that my schedule has been freed up for hopefully not too long, I was able to pull the pivot out of storage to check on those pins.
2, 3, 7 and 9 are apparently ground pins. Pin 8 is about 77 ohms to ground.
Pin 3 loses resistance when the screen is rotated so it must be the line from the mercury switch. (Portrait = ON, Landscape = OFF)
Pins 1, 4, 5, and 6 report no connection to ground.
Not sure what you wanted me to poke at with the DMM while the monitor is powered.
CelGen needs but try a stock, straight thru Mac Video Cable. I have some but they are being used for my KVM.

Good luck with the new job hunt, comrade.
I wonder if it will work either way from a standard VidCard at startup?
