Microsoft Windows 1.01 with CGA Display
---------------------------------------
[Microsoft Windows 1.01](/disks/pcx86/windows/1.01/), the first public version of Windows, was released on
November 20, 1985. It is shown here running on an IBM PC XT (Model 5160) with a CGA Display. You can also run
Windows 1.01 with a [Debugger](debugger/), [Soft Keyboard](softkbd/), or [EGA Display](/disks/pcx86/windows/1.01/).
{% include machine.html id="ibm5160-cga-win101" %}
The above simulation is configured for a clock speed of 4.77Mhz, with 256Kb of RAM and a CGA Display,
using the original IBM PC Model 5160 ROM BIOS and CGA font ROM. Even though the CGA was a "Color Graphics Adapter,"
the only CGA mode that Windows supported was the 640x200 2-color mode, hence its black-and-white appearance.
This PC XT configuration also includes a 10Mb hard disk with Windows 1.01 pre-installed.
This particular configuration will NOT save any changes when your browser exits, since it has
been pre-configured to always start Windows 1.01 in the same state.
NOTE: The Windows 1.01 mouse pointer can be controlled with your mouse, but only when your mouse is
within the "CGA Display" window. This is a restriction imposed by your web browser, not PCjs.
For more control over this machine, try the [Control Panel](debugger/) or [Soft Keyboard](softkbd/) configurations,
both of which feature the built-in PCjs Debugger, with save/restore enabled.
