I need somebody with a working voodoo 2 3dfx and a multimeter to help me with 1 measurement.

I need to compare the resistance to ground on one of the pins on a voodoo 2 3dfx on the graphics chip.

I got a voodoo 2 in pretty bad shape, looks like somebody has tried to resolder or re flow the the main chips, alot of the legs are not connected and 1 pin is missing.

I made a jumper cable for the missing pin and connected it, getting continuity to ground so really hoping this is a ground pin not the chip is shorted.
This is the chip

I am pointing the knife at the chip and the corner whree the pin is

And this is the pin I need the resistance for, obviously the ugly twisted one, not that the others are pretty

Yes I know C6 cap is missing, there is a few others but thanks to the v2 hw map on here won't be a problem 😀

thank you for the measurement. I fixed the pins and replaced the missing caps according to the ratings in the in the voodoo component map thread and it starts, don't want to say it works until I test it for a few days
