There are many like that system still present here, but problem is that you really probably couldn't find any PCI video card, only PCI-x for like fifteen or so years already. Thanks for letting me know this in 2019, cause It's really interesting case to see.
Mobos have evolved a long way.
Years back, you'd get up to 6, PCI slots.
Then came AGP... Accerated Graphics Port.... one of those for a video card + 5 PCIs
Then PCIE in x16, x8, x4, or x1 configuration. Mobos some various mix of those, plus 1 or 2 PCI slots for legacy.
Today, I have a workstation with 6x, PCIEx16 slots. (Not all wired with 16 lanes, of course.)
Scat, you have fallen into the IamaMars trap. Don't fall for it, the thread is dead.
