The first version of os/2, released in April 1987, was a text-mode only operating system, lacking the graphical user interface (‘Presentation Manager’) due to time constraints. The name of the operating system is derived from the new computer IBM was shipping, the ps/2 (personal system/2) I actually have an old ps/2 somewhere in the attic at my parents’ house.

Mensys, the online distributor of eComStation and other os/2-related products, was so kind as to provide OSNews with a review copy of this release candidate, and since my experience with os/2 and eCS is not much more than a few failed attempts at installing Warp 4, I was eager to try it out.
