Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Damn Small Linux 2024
ELKS supported MMU-less operation on 8088 and 80286 machines, but I don't think an ARM port exists: https://github.com/ghaerr/elks

SIIG MiniSys S286 Small Form Factor PC
Roughly in the mid-90s I bought at a local surplus store a "Carry 1" industrial 8088 computer which to my surprise I later discovered it could run Linux (ELKS: https://github.com/ghaerr/elks). I ultimately sold it on Ebay because although it was a beautiful piece of old tech, I was struggling to find more space for other things.
Here's one. I had only the central unit, mine had two floppy drives.

I don't think you can replace the OS on these. Unless there is a way to boot them from DOS, but you are looking at 8c086 machine so the choice is limited. Linux or BSD won't work. But ELKS might if it can be made to boot from DOS. Minix 2.02 seems to work.

Furby 1998 Source Code
Some small size Linux-like OSes do exist though: one commenter suggested Lunix (which I didn't know, thanks for the link), and a slightly bigger one is ELKS which runs on old MMU-less x86 CPUs. I managed to run it on a 8088 industrial PC ages ago.

I should have a Furby buried somewhere; now that I think of it, it may be the right platform to stick a bigger brain into, make it wireless so that it could be connected to the home IoT network then signal events or alerts.

Just a heads up, it looks like these guys ripped off Serge Kiselev's 8088 BIOS [1].

TinyBIOS – A minimalist open-source BIOS project for fun
There are at least three "real" 8086 BIOSes-- "real" as in they can work on actual hardware rather than just emulators-- available in source form, which might be worth examining.
https://www.phatcode.net/downloads.php?id=101 -- this is a respin of code that apparently originated in the 1980s in sketchy Taiwanese clones, so I think some of the docs are reverse engineered
http://glabios.org/ is an all-new-still-under-development project, but it works well enough for my hobby usage.
https://github.com/skiselev/8088_bios These are more targeted towards some specific hardware projects (Xi8088/Micro8088)
Obviously, being for a simple 8086 mrans they don't have some of the complex chipset config used in a modern PC, and even stuff like "hard disc support" is outsourced (for that, you might consider stuff like the XT-IDE Universal BIOS)
