Got rid of more app-specific demo machines (eg, DONKEY and WIN101); demos like that are more properly located in either the /apps or /disks folders (not /devices)

+The above simulation is configured for a clock speed of 4.77Mhz, with 64Kb of RAM and a CGA display,
+using the original IBM PC Model 5150 ROM BIOS and CGA font ROM.  This configuration also includes a
+predefined state, with PC-DOS 1.0 already booted and DONKEY.BAS ready to run.
+
+And now that PCx86 automatically saves all your changes (subject to the limits of your browser's local
+storage), you can even close the browser in the middle of a game of DONKEY, and the next time you load
+this page, your progress (and the donkey) will be perfectly restored.
+
+For more control over this machine, try the [Control Panel](debugger/) configuration, featuring the
+built-in PCx86 Debugger.
