To get the Apple Watch to launch Windows 95, Lee had to patch certain files within a WatchKit app to load his own application code.
With a 520 MHz processor, 512 MB of RAM, and 8GB of internal storage, the Apple Watch packs a lot of computing horsepower into a very small package. On paper, its processor alone is about twenty-five times faster than the average 386, and 512 MB was the size of a hard drive in the mid nineties, not memory. As a result, I was feeling confident that the Apple Watch had the ability to run one of the most revered desktop operating systems Redmond has ever produced.
Since it's run using the Bochs x86 emulator, it takes Windows 95 an hour to boot! Lee hot glued a motor to the watch's crown to keep it from falling asleep.
