July 20, 1978: Apple DOS makes its debut on the Apple II, giving Apple its first official operating system.
A command line interface with green text prompts on a black background, Apple DOS looks incredibly primitive next to today’s graphical user interfaces. Nonetheless, for Apple users this was the macOS Sierra of its day.
Older games that we all loved and played relentlessly as kids tend to disappear as the old operating systems that we played them on are sent out to pasture.
The Internet Archive, a free library of millions of free books, movies, websites, and other media, has also archived thousands of older MS_DOS games, like Maniac Mansion, Prince of Persia, and–yes–Oregon Trail, and has given us all access to them for free.
Turns out, you can still get dysentery while traveling to Oregon, even if you haven’t kept your old PC or Mac to play the seminal educational game on.
“The collection includes action, strategy, adventure and other unique genres of game and entertainment software,” writes Jason Scott, the Software Librarian for the Internet Archive. “Through the use of the EM-DOSBOX in-browser emulator, these programs are bootable and playable.”
Apple’s never been a particularly vocal advocate of open source, but thanks to a collaboration between two vintage computer museums, you can now delve into the sweet, sweet code of Apple’s first operating system.
