The man behind Slack’s development team Felix Rieseberg has recently introduced his another amazing transformation that is based on the conversion of Mac OS 8 into an app that users can now install onto their Mac and PCs.
The series of Rieseberg’s transformations date back to 2018 when he first transformed the old classic Windows 95 into an app. Now going one step ahead with his genius-ness, he has turned the entire 1991 Macintosh Quadra with Mac OS 8.1 into a single Electron app which includes all the apps and games which were originally a part of the operating system back in the days. Much of the credit has also been given to the old MacWorld demo CD from 1997 that has helped Felix a great deal in making this all a possibility.
Called as the macintosh.js app, the foundation of it is set on JavaScript. The app also uses a virtual machine that imitates the working of Macintosh Quadra 900 with the Motorola CPU - yes, the ones Apple used to operate with before moving to IBM’s PowerPC chips.
Once installed on your PCs, Mac or Linux, users would be able to enjoy a blast from the past in the form of games like Duke Nukem 3D, Civilization II, Dungeons & Dragons, Namely, Oregon Trail, Alley 19 Bowling, and Damage Incorporated. There are also pre-installed apps inside like Photoshop 3, Premiere 4, Illustrator 5.5, StuffIt Expander, and Apple’s Web Page Construction Kit.
Even though you will get the Internet Explorer and Netscape as a part of the app but according to Rieseberg, some of you might not get to open the softwares because the versions are too old.
Nevertheless, it still is a remarkable achievement to port 90s version of macOS and make it run in Javascript as well.
If any of you wants to try out the app for a trip down the memory lane then, fortunately, the complete versions are less than 250MB and you can download the app from GitHub.
