Exciting news for OS/2 fans: PCjs (v1.16.1) is now able to run OS/2 1.0 on
[IBM PC AT Machine Configurations](/devices/pc/machine/#model-5170-machine-configurations). This is the culmination
[IBM PC AT Machine Configurations](/devices/pcx86/machine/#model-5170-machine-configurations). This is the culmination
of recent work in PCjs to fully emulate the Intel 80286 processor and 16-bit protected-mode, including undocumented
features like [LOADALL](/pubs/pc/reference/intel/80286/loadall/) and triple-fault resets.
For a quick demo, try the [OS/2 1.0 Debugger Disk](/disks/pc/os2/misc/1.0/88286/). In a few seconds,
For a quick demo, try the [OS/2 1.0 Debugger Disk](/disks/pcx86/os2/misc/1.0/88286/). In a few seconds,
you'll see a very rudimentary OS/2 shell (a slimmed-down version of the OS/2 Program Selector) that allows you to
start the protected-mode command interpreter ("Start a Program") or the real-mode command interpreter ("command.com").

As an added bonus, the Model 5170 machines feature two serial ports, with COM1 connected to a simulated serial
mouse and COM2 connected to the **Control Panel** output window.

Once you've booted the [OS/2 1.0 Debugger Disk](/disks/pcx86/os2/misc/1.0/88286/) from the assortment of
[OS/2 Prototype Disks](/disks/pcx86/os2/misc/), you can click on the **Control Panel** output window, press Ctrl-C, and
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.
