cache is unobtanium Vram upgrade is pointless, what even is the VGA chip on this board? looks like something Compaq cooked themselves and got manufactured by LSI? Is it VLB? is it half decent? 4/66 means the only CPU upgrade possible is with Overdrive or one of those https://www.vogons.org/viewtopic …

Afaik Quadro and Ultra are using same pcb design with SC1175 regulators? Those are able to report brownouts. Its possible Quadro bios being more fancy actually monitors that.

Afair Transport Tycoon did water with palette cycling, everything else was VLB brute force. I dont think it is doing any fancy VESA panning, I dont think VESA even had any panning standardized in early versions (1-1.3).

Siemens office box and ECS. Great picks! FYI, PCChips took over ECS in 1998, so its pretty much a pcchips with different logo. >It seems to be power delivery problems through AGP slot? Test continuity between ATX 3.3V pin and AGP 3.3V ones.

Capacitor starts shorted until it charges up - thats how most early Reset circuits work. Much simpler than weird circuits with relays.

What am I supposed to be seeing on this photo? other than maybe a chipped resistor/capacitor? One way bad card can blow AGP is by shorting 3.3V and frying a track between AGP and ATX connector
