IBM PC Running DONKEY.BAS
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 includes a predefined state, with PC-DOS 1.0 already booted and DONKEY.BAS ready to run. A Control Panel configuration is also available, featuring the built-in PCx86 Debugger.
This particular machine has been configured to automatically save all your changes (subject to the limits of your browser’s local storage), so you can close the browser in the middle of a game of DONKEY, and the next time you load this page, your progress (and the donkey) should be perfectly restored.
