All — I haven’t been able to talk about this early MSDOS recovery project since a few of us began working on it in September, but you can see the blog post by Scott Hanselman here. Scott’s post links to both @BrokenPipe’s site and mine where we discuss the process. In short, I was able to get 700-ish pages of original source listings from Tim Paterson which I scanned and then we converted to workable source code. It’s the earliest known version of DOS code to exist in the wild. https://opensource.microsoft.com/blog/2026/04/28/continuing-the-story-of-ear...
