I had to just go find the details for the original 386 Unix server [1] I was running ~1995 because I thought it was running just fine on 8MB RAM, running an EFnet IRC node, FTP, MUDs and some early web apps. And... yep, 2 x 4MB SIMMs. Wild times. A single photo from my phone is three times that size.
(I later took that PC home and used it as the test machine for my own hobby OS, which had to run from a 1.44MB floppy because there was no other sane way to transfer the dev images from my desktop)

Wow 8MB of ram… that’s really amazing! Which hobbyOS did you made?
I named it Tinkerbell for some reason. It was kinda neat, it would boot directly into a windowed GUI. It lived at tinkerbell.org back in the 90s, but it seems it got missed by archive.org :(
