I picked this up from a scrapper years back who had 'harvested' the ribbon cable with the VGA connector.
If you have this card, would you please Ohm out the header to the DSUB connector. I already have the parts necessary to construct a custom cable.
Thanks.

Isn't left pin on top row marked as "1" ?

Here's what it looks like:
Now, according to this photo of a general HD15 pinout, pins 4, 9, and 12 are not used:
You make a good point, if that's pin 1, then the pinout follows logically... But I have 13 pins, what combination of two pins of pins 4, 9, and 12 should I leave out then?
Thanks

aren't the analog pins connected to the dvi ones ? ie measuring continuity between the pin header and dvi pads should give easy results.
since there's no backside visible i'm assuming that the dvi connector is only lacking the pins, but the pads/holes are available on the pcb under the connector and on the backside.
Right to repair is fundamental. You own it, you're allowed to fix it.

Unfortunately (but by design) not as such, it's DVI-D, so while there is continuity (because I assume they probably share some signals), there's no correlation with all the pins.

Did you look into it?
for VGA all one would need would be R,G,B,hsync,vsync,gnd, ddc_data & ddc_clk
Those would correspond to pin C1, C2, C3, C4, 8, C5, 7, 6 on the DVI connector.
that's only 7 signal pins, the rest are likely to be ground anyway.
though if the pads for the full DVI-I layout on the backside of the pcb are missing, my whole suggestion is moot anyway.

Indeed! The pads are there! (six pads). Ok, I'll Ohm these out later on and report back! Thanks
