I'll have to check my Compaq Deskpro XL466.
It's a very late 486, with PCI and 72-pin DIMMs and all. It's also very high-end (workstation-class), with onboard LAN and SCSI.
I wonder how much memory that one could take.
Here's a Russian page on it with good pictures: http://ru.pc-history.com/compaq-deskpro-xl-466.html
Note that the CPU, chipset and memory are on a special expansion board.
I have a Deskrpo XL6200 as well, which is a Pentium Pro 200. It's basically the exact same machine, apart from that CPU board. I even tried swapping the CPU boards between the machines, and that worked fine.
Edit: According to this, it's only a measly 128 MB for the 486: https://support.hp.com/hr-en/document/c00355459#AbT0
