Hello! On your blog Rich concerning the older MS-DOS reconstruction efforts, regarding Ray Duncan. He's an author who wrote of my books on programming in that environment, which is "Advanced MS-DOS Programming: The Microsoft Guide for Assembly Language and C Programmers". It was really helpful when I got started, using Borland's TASM products in fact. And if you have a copy look in the back at how it was published, the tool used was the CCI system which originally ran on a DG Nova, rewritten for the MS-DOS world. (I think. My dad's efforts to track that down for me did not lead to any useful clues.) Anyway that's an amazing book. ---- Gregg C Levine gregg.drwho8@gmail.com "This signature was once found posting rude messages in English in the Moscow subway."

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.
