本文介绍了微软开放源代码博客上的一个事件，即微软开放了 MS-DOS 4.00 的源代码，并将其发布在 GitHub 上。这个版本的历史相当复杂，微软与 IBM 合作开发了部分代码，同时还创建了一个名为 Multitasking DOS 的分支，但这个分支并没有广泛发布。文章中提到了一位名叫 Connor "Starfrost" Hyde 的年轻英国研究人员，他联系了前微软首席技术官 Ray Ozzie，讨论了他收藏的一些软件。Ozzie 在他担任 Lotus 期间收到了 DOS 4.0 的未发布测试版本，他与 Starfrost 合作，探索发布 DOS 4 的源代码。微软和 IBM 认为这是操作系统历史上一个值得分享的重要片段。文章还感谢了那些为数字考古做出贡献的人，包括 Greaseweazle、Fluxengine、Aaru Data Preservation Suite 和 HxC Floppy Emulator 等软件的开发者。最后，作者斯科特·汉森（Scott Hanselman）提到了他自己的背景和联系方式。

sponaugle: As Scott mentioned in the blog post, we were able to get this running on one of my original IBM XTs with an original IBM monochrome display adapter and display. It was very cool to be able to switch between a running version of a small game, Turbo Pascal, and a DOS prompt with a single key press.<p>It is always great to have period software on period hardware!<p>(added: Short video of it running - <a href="https://www.youtube.com/watch?v=YPPNbaQaumk" rel="nofollow">https://www.youtube.com/watch?v=YPPNbaQaumk</a>)

sponaugle: 正如Scott在博客文章中提到的，我们能够在我的一个原始IBM XT上运行它，该XT具有原始的IBM单色显示适配器和显示器。能够在运行版本的小游戏Turbo Pascal和DOS提示之间切换是非常酷的<p> 在时代硬件上安装时代软件总是很棒的<p> （添加：它运行的短视频-<a href=“https://；&#x2F；www.youtube.com&#x2F？watch？v=YPPNbaQaumk”rel=“nofollow”>https://；#xx2F；http://www.youtube.com#xA0；watch？v=YPPNbaQaumk</a>）

jmspring: My brain is rusty, but I feel like MSDOS 5.11 was where things finally just worked. TSRs, memory managers, etc. Moving a lot and not being a packrat I've lost some of that history.<p>It'd be interesting to see 5.x and 6.x released.

jmspring: 我的大脑已经生疏了，但我觉得MSDOS 5.11终于发挥了作用。TSR、存储器管理器等。移动很多并且不是packrat I；I’我失去了一些那段历史<p> 它；我很高兴看到5.x和6.x的发布。
