find yourself magically transported into the OS/2 Kernel Debugger. The **Control Panel** display is functioning
as both the output window for all PCjs messages and PCjs Debugger commands, as well as a serial input/output device
(aka "Dumb Terminal") for any software inside the machine communicating via COM2: in this case, the OS/2 Kernel Debugger.

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](/disks/pc/os2/misc/).

Below are some interesting pre-1.0 (or 1.0-based) OS/2 revisions we have unearthed. They provide an early glimpse
of OS/2 when it was still a work-in-progress. Not all of the disks run properly in PCjs yet, but we're working on it.

The [OS/2 CP-DOS Boot Disk (v7.68)](/disks/pc/os2/misc/cpdos/86295/) contained a pre-1.0 version of OS/2
