Products that do what My self-written hobby OS is finally running on my vintage IBM ThinkPad does
Finally got my hobby OS up and running on real hardware. I love the old IBM thinkpads, so thought it was the perfect machine to get it working on. Been working on it for quite some time now, but this has been a big milestone!

Hello! I'm Byran. I spent the past ~6 months engineering a laptop from scratch. It's fully open-source on GH at: https://github.com/Hello9999901/laptop

To try it out, simply build the project yourself from source, or use attached bootable ISO image of the system (in Releases on Github) and run it in QEMU. https://blog.vxn.dev/rou2exos-rusted-edition

I've wanted to make my own OS since I started programming. Now, 5 years later, I did it (kind of). Sure, it is really basic, has very little functionality, but I made it and I'm proud of that. Oh, and I'm just 16 btw.

Not sure if I would post this for the last day of #marchintosh OR wait for tomorrow the 1st of April. Both apply equally. Anyway, here's a pet project of mine, I made it as a glued on for another pet project of mine, but it developed a life of it's own now and can soar skyward toward success, fame, and glory.

https://lisagui.com/info.html This is a web OS I wrote in vanilla JS that looks like the Apple Lisa Office System (1983-85), with other contemporaneous influences and additional improvements and features. It's currently in alpha and isn't remotely bug free. I had been holding off on posting this here until it was somewhat presentable and useful. Please note; the Lisa conforms more literally to the desktop metaphor than most modern GUIs - some of the important differences are mentioned in the readme. This is a complete recreation of the UI in JS; it all renders to a single…

A while ago I was looking for information on a obscure and short lived British computer. I found an article[1] in the archives of BYTE magazine[2] - and was captivated immediately by the tech adverts of bygone eras. This led to a long side project to be able to see all 100k pages of BYTE in a single searchable place. [1]: https://byte.tsundoku.io/#198502-381 [2]: https://news.ycombinator.com/item?id=17683184

Hello. I wrote a multitasking 16-bit real mode "operating system" that works on every IBM PC compatible computer, and a TCP/IP stack for it. Then I wrote an HTTP server for it.

Hello HN, I've been working on a simple OS for tinkering and running bare metal apps on vintage PCs. Since I couldn't quite decide whether to target pure 16-bit, or slightly more capable 32-bit machines, I ended up with two separate versions: - GentleOS/32 (https://github.com/luke8086/gentleos32) works on i386+, requires 4MB of RAM and VGA display supporting 640x480x16 mode or any 256-color VESA mode. - GentleOS/16 (https://github.com/luke8086/gentleos) works on 80186+, requires less than 192KB of RAM and a CGA display supporting 320x200x4…

Just wanted to make my first post about something interesting I've been working on for some time. Any ideas/suggestions for new hardware or software I should try out are welcome, though I will only have time for a major overhaul in a month or two where I want to redo and document everything a bit better than how it is currently. Hope this can inspire someone to start their own homelab or give some ideas to already existing ones!

You know that old TI calculator you used in high school, then put in a box and forgot about? Have you ever wished you had an operating system for your calculator with preemptive multitasking, dynamic memory management, a tree filesystem conforming to the FHS, and all the comforts of Unix? Well, good news: that's totally a thing that exists. I've been working on my kernel for about three and a half years now and I'm looking for new contributors to help out. It's written entirely in z80 assembly, and it's both challenging and fun to work on. There's an IRC channel for contributors or people…

Since it appears to be retrocomputing day on HN, I thought I'd post my pet project. It's a collection of modern peripherals for retrocomputers. I started collecting a list of upgrades for my ideal dream Mac SE/30 and grew from there. The site is currently mostly focused on Apple II and Mac stuff since that's what I grew up with.

This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality. At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root…

Hi All. I made this as an fun intro to help people who have zero IBM mainframe experience and no access to a modern IBM mainframe (at least, not access to do whatever you want with it). I appreciate tips, suggestions and anything that might improve the experience for someone who has no idea of how those machines operate(d).

Hey gang, My names Ryan. I Develop Desktop applications, usually for Windows. I made this little Trainer application , if anyone wants to try it out. It lets you manipulate values in memory, in-order to hack stats, crafting materials, etc. If you like it, have any suggestions, or angrily yell about the console release, feel free to hmu. https://github.com/howzitkiffen/Cyber-Punk-Trainer (PS: Looking for work!)

VibeOS is a retro operating system that boots on qemu and Pi Zero 2W. I built this with Claude code in about 4 weeks.

Made an ARM Thumb CPU from scratch in a digital circuit simulator for fun and decided to push the joke a little further and run real stuff on it, like a Web server, a Scheme interpreter, a MIDI player, and a VT100 emulator. This is basically a how-did-we-get-here blogpost, it's my second one of this kind, I'd love any feedback you might have.

Democratisation of local AI is key. I've been working on pushing the limits of commercial hardware, squeezing any extra bit possible. My Scientific Agentic AI hareness helped me to reallocate every single bit of it. I rewrote the Kernel, I went down the CUDA rabbit hole until I have been able to explain any bit and any ms of computational power involved in the process pushing the Qwen 30B-A3B from 8 tok7s to 19 tok/s with llama.cpp up to 22.2 tok/s with my project and 109 tok/s on not novel content and speeding up the prefill by 5-9X
