That takes me back.

I'm surprised there aren't more hand-crafted OSs popping up on HN. Agentic AI can give you the basics of an OS in 15 minutes. It gets confused when debugging assembly code, but it can give you a good framework and walk you though the remainder of the steps.

I threw myself at it for weeks and couldn't even get a blinking LED to run on the bare metal on a RPi.

I am intrigued. Go ahead and show us ONE 15 minute agentic ai os that runs on metal.

The parent commenter should get an Altair Z80 emulator with CP/M 2.2 and begin writting stuff in assembly.

Even a simple Tetris would be a daunting task.

He could even try high level languages such as T3X, which is very Pascal-like to my eyes in order to be familiar with CP/M 2.2 and after some months I would switch to Z80 assembly in order to write stuff for CP/M.

These AI's would be clueless about T3X OFC, or almost, because of the nasty scrappers. Still, it would be an ideal exercise to avoid the AI completely. You learn by the book. Literally.

Wait, I'm confused. Why would I use an obscure language that no one knows about, or could find a book on, when I could just have the AI write Z80 assembly, or even have it make a Z80 C compiler for me? (You laugh because you haven't tried it)

The biggest problem on today's OS is I/O driver. Specifically USB driver.

And ACPI/APIC and tons of extra pests.

I am amazed they got that far without having support for an UART.

Naive question: would using such an OS bring some security by obscurity ?

It’s short for “visual operating system” but there are no screenshots anywhere. That would have felt off even in 1997.

Maybe they mean something else by visual.

Around 1997 I learned the concept of RTFM! Obviously my father already taught me to look in the DOS and WordPerfect manuals to learn about features and commands one might use. Great learnings.

Oh and:

> Great learnings.

Lessons. The word is lessons.

wjnc 11/4/2025||
Haha, have you missed your etymology and poetry classes? A lesson is something you learn. A learning is an act or experience. A joke telling someone of when you’ve learned to RTFM is intended to feel like a yoke.

In the homepage there's literally a link on the top bar called "Screenshots"

Just use temple os

TempleOS with a BeOS GUI - that's the vibe

By now, especially in linux, there should emerge an OS that is purely scripts to generate OS. Or is it already ?
yjftsjthsd-h 11/2/2025||
Depending on how you mean it, that exists variously in at least yocto, gentoo, or ALFS. Although I should point out this (visopsys) isn't Linux distro

NixOS is what you are describing: https://nixos.org
