If you are anything like me, having a computer class in elementary/high school in the early to mid 90s was less of an excuse to learn how to use computers, and more of an excuse to play video games at school.
One such game that masqueraded as an "educational" experience was The Oregon Trail. Now to be fair, The Oregon Trail is about as educational as today's Assassin's Creed series, but it was a lot of fun and a great way to waste an hour of a day.
Now you can relive the memories of those disks spinning up and showing that MECC logo in a modern web browser! The Internet Archive, the library of all things digital, has added in-browser support for emulated copies of many pieces of old software including a lot of your old favorite games. Oregon Trail, check. Carmen Sandiego? Check. Prince of Persia? Check. Heck, they even have the original Sim City! The library is actually surprisingly extensive. You need to check it out!
One small bit of warning. Don't let the kids roam around on here, there is a bit of adult software in here as well. Also, my apologies if I've just wasted a couple of weeks for you. But hey, you had fun!.
