OS/2 and eComStation "Co-developed by IBM and Microsoft, it was intended to replace DOS, the aging software that then powered most of the planet's microcomputers. It never did. Instead, Microsoft's Windows reinvigorated DOS, helping to end IBM's control of the PC standard it had created. By the mid-1990s, IBM had given up on OS/2 - a major step in the company's slow-motion retreat from the PC industry, which it completed in 2005 by agreeing to sell its PC division to China's Lenovo. But while OS/2 never truly caught on, it's also never gone away. Even if you believe that you never saw it in action, there's a decent chance that you unwittingly encounter it at least occasionally to this day." The last time I took a look at eComStation was way back in 2007.

I thought the article said that OS/2 2.2 needed 6mb of ram. I think we had four, or two. I can't remember exactly, but it wasn't 6 or above. I would imagine that OS/2 3.0 Warp would be the same or require more memory.

I ran OS/2 2.0 on 4MB quite comfortably on a 386 for quite a while back in the day. I have seen references stating that the minimum RAM requirements for version 2.1/2.11 were 6MB, but prior to that version it was always 4MB, and the version 3.0 (Warp) was also 4MB.

I believe this was because the version of Win-OS/2 (the Windows subsystem) changed from using Windows 3.0 (which used 8086 real mode) to version 3.1 (which used 286/386 protected mode) with 2.1.

This change involved some surgery on Windows itself. Parts of Windows 3.1 were customized in order to function properly on top of OS/2, where as Windows 3.0 could run practically unmodified on a standard DOSBox session.

Since Windows 3.1 needed more memory than Windows 3.0, that increased the minimum to 6MB if you used Windows Application. OS/2 itself did not ever need more than 4MB until Warp 4.0 (although 4MB was pushing it for v3.0, especially if you actually used TCP/IP).
