Thanks to mathj for sending these out for scanning.

Most excellent!

Maybe this will reveal some clarity on dumping/flashing the mother board without desoldering the flash chips.

I was googling for schematics for a Tekken 2 (System 11) motherboard I have with issues and your post just showed up, for me this document makes the difference between being able to continue troubleshooting the board and hopefully finding the issue or throwing it into the parts bin for maybe later fiddling, since it is very tedious to figure out stuff without schematics, especially in between custom ICs. As far I can tell I see you are the first person to make available these very useful documents that nobody could (or wanted?) to scan and share since 25+ years, so, thanks a lot!

It's definitely possible, I know a guy who did it some time ago.
