In case anybody is wondering….PCI slot #1 is completely useless! It is blocked by the big green capacitors and heat sinks!!
The only card that could go in there is one of those odd shaped ones - those are typically sound cards. Upon further inspection - no card can fit there.
I don’t think there are any more video upgrades physically possible. There’s just no room. I’m happy onboard video is passable. I’m also lucky that the onboard sound card has DOS drivers for MS-DOS mode. There’s just no more room for anything else in the case.
