I realize that ATX standart came about long after 486's heyday, but there were a lot of 486 boards still in production throughout the Socket 7 era, so I was wondering, has anyone produced ATX 486 boards?

$125.. with $233 shipping no less.. And it apparently lacks the processor board.. I said Wow. Not that I expected to find them cheap, but knowing they exist gives me a new purpose. 😎

I'm not sure if this really counts. It looks like a purpose built server board (EISA and seperate processor boards). Even power connector is not ATX.

Yea, I have a Compaq Deskpro XL466 which looks a lot like that... It has the CPU (and part of the chipset) on a special board, and it has the connections on a panel at the back, like ATX, but I don't think it's standard ATX.
It seems to be some weird proprietary form factor.. works with AT PSU for certain.
That of course is the case with the above ebay listing as well, now that I notice.. The ebay listing actually does not use an AT PSU, it's a proprietary AT + 6pin..

its the closest i could find on google in 5 minutes 🤣, but its close to ATX, i'd call it ATX .5
Both of these boards have AT P8/P9 (+AUX) power connectors and it looks like the expansion slots also aren't (all) in the regular ATX position. So I'd call this a forerunner of ATX rather than ATX itself. Still, there's more than enough overlap between real ATX boards (starting late 1995/early 1996) and the last mass-market 486 boards, so the search is on as far as I'm concerned 😉
