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.
