Before OS/2 was named OS/2 by IBM on April 2, 1987 (as part of IBM's "Divide By Two And Conquer" initiative), OS/2 was known variously as CP-DOS, MT-DOS, DOS5, or ADOS. Or, when referring to 80286-only and 80386-only versions: 286DOS and 386DOS.

And then there were all the early codes-names, like SIZZLE, PIGSKIN, and FOOTBALL, which were little-known projects to help improve and/or shape the direction that OS/2 was headed.

To shed some light on those efforts, I recently added a small collection of early (mostly pre-1.0) OS/2 boot disks that provide a glimpse of what early OS/2 builds looked like.

More details are available in OS/2 Prototype Disks.
