The earliest DOS source code was found on printer paper in Tim Paterson's garage so we've open sourced it on 86-DOS 1.00’s 45th anniversary! This is next-level software archaeology for preservation, and plain ol’ curiosity. #DOS #RetroComputing

The earliest discovered DOS source codes have been recovered!

As a continued effort to preserve some of the oldest computing artifacts, such as the UNIX 4th Edition tape discovery that happened as 2025 was coming to the end, Microsoft has continued to give access to the source code of old versions of MS-DOS, such as version v1.25 and v2.11.

Today, on April 28th, Microsoft has made a huge announcement that will excite those interested in retrocomputing in a way that never happened before. Microsoft has finally released the source code of the earliest DOS versions discovered!

You can see the GitHub page of the source code here.

Open the source code

Those newly-available source code materials that provide an early look of how PC-DOS 1.0, the first DOS for IBM PCs, was developed, as a celebration of the 45th year anniversary of the antique operating system. This collection of such materials, such as e-mails and other documents, were done by a team of historians and preservationists, with the leaders being Yufeng Gao and Rich Cini.

The team has located, scanned, and transcribed the stack of DOS-era source listings from the author of DOS, Tim Patterson, which are now available in the MS-DOS source code found on GitHub. Those listing include interesting bits, such as development snapshots of the PC-DOS 1.0 kernel, sources to 86-DOS 1.0 kernel, and utilities like CHKDSK, a program for checking your disk for errors.

This is such a huge discovery and preservation that was done, and anyone who’s interested in seeing those artifacts in person will be able to do so by visiting the Interim Computing Museum in the next coming days.

Yeah, after just 27 years, I am again contributing to an official demoscene release (yeah, there is a point in time when you realize: indeed - life is short :) ).

Rabenauge / Bitshifters: "Chipo Django #3"

a kewl 16 Bit #musicdisc with a twist: It's released on #AMIGA, #ATARIST and #ARCHIMEDES in parallel!

It feels unreal to be right between 2 kick ass tunes by FILIPPP and NOMISTAKE and on one disc together with legends like Vincenzo or Chavez.

More details at the Peertube description, including the download link of the disc image(s). AtariST/Amiga/Archi in one Zip.

This is my track only, the complete video recording of this disc will appear later on Youtube and the likes, I am sure.

Thanks to @bodohinueber (a superpowered Commodore coding wizard who did the Amiga port here) for having me!

I'm looking to connect with the #retrocomputing community here in the fediverse because I'm restoring an #appleii and I really want to avoid things like youtube, reddit, etc.

I know this makes it hard, but frankly, those places suck and if I have to choose between going there and doing it all the hard way, fine.

But I really think there's a third way here in the fediverse, and I'd love to prove it 😁

If you're hacking on Apple II machines, I want to hang out.

Bring back amber screens, I say!
