This isn’t the first time Riseberg has had a swing at OS emulation. A couple of years ago he did the same thing with Windows 95, so it would seem only logical to jump on another classic OS – this time on the Macintosh side of the fence.
macintosh.js as he’s named it emulates a 1991 Macintosh Quadra running Mac OS 8.1. It is, in his own words, something that probably should’ve been built natively, but has instead manifested itself as an Electron application.
You can download the application from Rieseberg’s github account here.
