Hello everyone!

I’m slowly resurrecting a 486 dx2 50 machine and having some issues with the graphics card, here’s a video of what it’s doing:

Card is a Diamond Stealth32 VLB with 2mb of memory, it seems to put vertical bars over certain colours.

I’ve tried changing the slots, cleaning the isa/vlb connector, moving round system memory just incase.

Only things I can see that look a bit odd is C53 is connected across one of the pins on the STG1702J, and it also appears to have a fixed trace, both appear as if they were done from factory but not 100% sure.

I’m super grateful of any help or ideas anyone has!
