I worked in a college computer lab with PS/2 systems that had OS/2 1.X on them with the option of booting up PC-DOS as well. After that I worked at a tools company that had OS/2 2.X systems on PS/2 systems and we upgraded them with Kingston Microchannel cards that added more RAM and used IDE hard drives. Using Client Access/400 for DOS/Windows ate up the 640K of DOS RAM, but in OS/2 it used the memory above 640K so more of it was free. It was the AS/400 client software that we needed to access DB2 databases and other things. We also used Token Ring and was a big IBM shop. Until management decided to switch to MS-DOS 6.X and Windows for Workgroups 3.11 with MS-Office 4.3 to get everyone on it standardized because they got a bulk discount from 800 Software. The IBM PS/2 systems got replaced with Compaq and Gateway 2000 systems that were cheaper. We also used Windows NT 3.1 and switched to Windows 95. I was downsized in 1995 before the Windows 95 roll-outs. But I had OS/2 experience that got me a lot of job interviews, like Enterprise Rent-A-Car used OS/2 and I almost got hired there. OS/2 was phased out and in 1995 I couldn't get OS/2 3.0 Warp working with my 486DX PC clone so I got Slackware Linux instead. OS/2 3.0 Warp lacked driver support for certain hardware and that was the downfall of OS/2 from 1995 and on. Edit:Typo
