OS/5 - The forgotten Microsoft-based PC operating system

OS/5 is a Shareware PC operating system based on a Microsoft programming language that itself was rarely used. Intended to be an inexpensive, lightweight alternative to Windows, OS/2, and other graphical user interfaces, OS/5's Desktop runs in text mode while retaining many GUI features. Created by John Poole and released in 1996, two versions of it are known to exist, and would have been lost entirely if I had not saved them over 25 years ago, because they have not been archived anywhere online and trying to search for OS/5 or its author will turn up nothing except this video.
