You know what they say. You snooze, you miss out on a DOS emulator in the Apple App Store. That rare and unimaginable occurrence happened earlier today, when the so-called iDOS emulator was briefly available for both the iPhone and iPad before it was unsurprisingly pulled from the store a short time ago. That wasn't before it was seen spotted running Windows 3.0 and even some classic Sierra adventure games, though -- head on past the break for the evidence.
