I had almost the exact motherboard between 1994 and 2012 that had real L2 cache and an AMD AM486-DX4 120 CPU in it. That was a beast, until the BIOS chip died (Award, aka, the "Y2K bug" BIOS that was on a PROM chip).
You can, however, desolder the fake L2 cache, remove the solder leads that serves as the L2 cache size and make it into a motherboard with real L2 cache:
And, if needed, you can desolder the BIOS chip carefully and purchase an IC socket like this: https://www.digikey.com/product-detail/ ... ND/4147603 (Digikey part number: ED3053-5-ND).
Also, I found a SIMM-72 slot: https://www.digikey.com/product-detail/ ... ND/1639981 (Digikey part number: A114049-ND) in case you're interested as well.
Oh no sir, this will be going on the hardware giveaway thread since it works fine and someone might like a project like what you speak of.
