Earliest version of MSDOS recovered
by Richard Cini 01 Jun '26

01 Jun '26

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-ea… Rich http://cini.classiccmp.org/ https://github.com/RichCini Long Island S100 User’s Group Get Outlook<https://aka.ms/qtex0l> for iOS

UK Atari STE on US via 240V transformer (50 vs 60 hz)?
by John Heritage 31 May '26

31 May '26

Hi folks, I'm importing an Atari STE from the UK, that requires 240V. I have a 120V to 240V transformer, and was wondering if that would work, or would there be a problem because the UK's grid runs at 50 Hz while the US grid runs at 60 Hz. I plan to replace the internal power supply with a modern 120V solution, but wanted to test the STE out of the box before I replaced the PSU. Thanks! John
