considerations for OS/2. Up to this point, all OS/2 design and development work had been 16-bit, since the
state-of-the-art Intel CPU at the time was the 80286.
The FOOTBALL prototype was forked from pre-1.0 OS/2 sources, and the only hardware it supported was the Compaq DeskPro
386-16. The source code was later sent to IBM, and as of April 1987, they were adapting it to run on the Model 80 PS/2.
It is unlikely that any FOOTBALL prototype was ever released outside of Microsoft and IBM.
The FOOTBALL prototype was based on pre-1.0 OS/2 sources, and the only hardware it supported was the Compaq DeskPro
386-16. The source code was later sent to IBM, who in early April 1987 was adapting it to run on the Model 80 PS/2.
Although FOOTBALL contained features not found in OS/2 until version 2.0, there is no direct connection between this
internal Microsoft effort and OS/2 2.0. Some of the 32-bit support and paging work undoubtedly migrated to version 2.0
eventually, but that would have happened much later, since work on OS/2 2.0 did not begin in earnest until October 1987,
after 1.0 was finished.
After OS/2 1.0 was finished in October 1987, FOOTBALL changes were merged into a fresh set of 1.0 sources, which
initially was version 1.3 (also known as **PIGSKIN** and later **CRUISER**) but ultimately became version 2.0.

The numbering of revisions must have been, um, revised, because despite the lower revision (4.41.00 vs. 7.68.17),
