Couldn't find any data on this combo.
Trying to find this or same pinout to check connections on a motherboard.
Thanks for any help.

newest UMC databook is from 1991 and does not cover that chipset. Many have looked for the datasheet and it remains elusive
Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
I wanted to check cache connections to chipset and cpu.
It's on a 486 motherboard.
So annoying 🤣
Now I have to learn which address and data lines I have to check in order to rule out a broken trace.
Still a win but deserves cake.

I have found Intel 80486 pinouts and there are two different buses, 25/33 and 50mhz.
If I have the addresses involved in L2 cache and this pinout, before I waste time, is it safe to assume that I'll find all connections and can check if cache is in fact communicating to the cpu? (ok, it's not that long of a sentence),
or
there is some chipset connections I have to check too?
I have very little time in the coming weeks and I want to sort out this non working L2 cache.
Thanks

I guess unless someone finds these documentations, the only way to solve this issue will be retro-engineering.

I am surprised, by now I thought it would have been out and available to the general public.
Probably these mysteries will never be solved 😀
Guess I'll go slow as a snail and learn something from it.
Last thing, is there a free program to create interactive datasheets, like the ones you see in reapair shops when doing Apple laptops, where you click on a component and it gives you all the connections spanning from?
Worth doing.

I checked connections and all is working.
Issue, after months of ???, was a solder joint that, when pressing with probe, would make contact and otherwise not make contact.
Banging my head on the wall so hard neighbours are worried 🤣 🤣
Guess learning is hard way only for me.
