There’s even a bunch of apps and trials preinstalled, including Photoshop 3, Premiere 4, Illustrator 5.5, StuffIt Expander, and Apple’s Web Page Construction Kit. Rieseberg has managed to get classic games like Duke Nukem 3D, Civilization II, Dungeons & Dragons, Namely, Oregon Trail, Alley 19 Bowling, and Damage Incorporated running. The macintosh.js app is written entirely in JavaScript, and it uses a virtual machine to emulate a Macintosh Quadra 900 with the Motorola CPU Apple used before its transition to IBM’s PowerPC chips. The app can be installed on macOS, Windows, and Linux. It even includes a number of apps and games, thanks to an old MacWorld demo CD from 1997.
Rieseberg decided to turn an entire 1991 Macintosh Quadra with Mac OS 8.1 into a single Electron app. macintosh.js is Mac OS 8 running in an Electron app pretending to be a 1991 Macintosh Quadra. Slack developer Felix Rieseberg has transformed Mac OS 8 into an app you can install on your Mac, a crappy Windows PC, or even on Linux.
