	This stream was primarily to experience the original 1.0 release of OS/2, since it was both considerably different that OS/2 1.1 (which included Presentation Manager), and was probably the closest to the original vision of Advanced DOS and/or MS-DOS 5. It also serves as a reference point, to understand all the things that came before and after, for example, how Multiuser DOS influenced things, and what cracks were visible at the time.

	A useful line of thought is to see what support guarantees were given in regards to older DOS environments, as well as determining, in practie, when support for the 8088, 286, and 386 faded away. In practice, from what I've seen, 8088 based systems seemed to have lasted until the release of DOS 5, the last one on 5.25 disks in the early 90s. Use of the 286's protected mode generally came with the general availability of Windows 3.0 and 3.1, with these systems only being retired with the advent of Windows 95, with the 386 and 486 leading the charge from there.

	By and large, OS/2 wasn't intended for end-users at this time; this was closer to developer release or business release, as a cheaper alternative to Xenix. I created two scenario examples, one of a Microsoft employee doing operating system development, and one of IBM providing it as a low cost alternative to a mini-computer. To that end, we looked at IBM OS/2 Extended Edition, which for OS/2, included Database Manager, Query Manager, and Communication Manager; applications you would expect to run in medium sized business that had need of such things.

			Throughout the stream, I noted differences between the environments, how the system was put together, and tested several scenarios and compatibility issues as documented below.

	Microsoft seems to have been working on a true successor for DOS for microcomputers, first with Multiuser DOS 4, and then OS/2, using the 80286's protected mode. This is evident with the MS-DOS 4/5 naming scheme, and it was likely that Microsoft was prepared to support multiple DOS versions in parallel, similar to how Apple de facto supported DOS 3.3, and ProDOS on their 8-bit line of computers.

IBM meanwhile seems to have been working on the lowest tier end of their business products. Most of IBM's contribution of OS/2 seems to be in the form of a revised installer, and the IBM specific applications such as Database Manager, Query Manager, and Communication Manager. While IBM did sell machines intended for purchase by home users, these were generally done through a dealer and not to an end user directly, as LGR documented in his PC AT setup video.<ref>https://www.youtube.com/watch?v=nLy_jEbuY-U</ref>

	While it might be my initial basis showing, the impression I've gotten, especially taking in the differences between IBM and Microsoft OS/2 in to consideration is that both companies had very different ideas on where they were going to take it. By and large, end-users seem to be something of an afterthought, since the lack of applications and cost of memory would have excluded OS/2 to all but the very top tier of power users. In addition, Microsoft would continue to supporting 8088 based systems until the 90s, with the release of Windows 3.0 and DOS 5.
