Macintosh.js is not Rieseberg's first program to simulate old operating systems. Although the app includes Internet Explorer and Netscape Navigator, the emulator cannot connect to the internet. It can also mount disk images and transfer files from your current drive into the virtual Macintosh. In addition to what comes preinstalled, Rieseberg says that any compatible software from that timeframe is installable (if you can find them).

Remember those? The classic Oregon Trail makes an appearance as does Duke Nukem 3D, Civilization II, Alley 19 Bowling, Damage Incorporated, and Dungeons & Dragons. The app includes several old software packages that one would have found for Macs of that era, including Photoshop 3, Premiere 4, Illustrator 5.5, StuffIt Expander, Apple's Web Page Construction Kit, and others.Ī handful of preinstalled game demos come with it, which Rieseberg culled from an old 1997 MacWorld Demo Disc. However, Rieseberg made the files and resources available on GitHub 'for educational purposes only.' Whether his disclaimer is enough to keep Apple's lawyers off his back remains to be seen. You won't find it on Apple's App Store because Cupertino bigwigs have not approved it. The Quadra 900 was launched in 1991, so we're stepping back almost 30 years. It is essentially a virtual machine that emulates a 1990's pre-PowerPC era Macintosh Quadra 900 equipped with a Motorola processor. The app is called 'macintosh.js.' The '.js' suffix is appropriate, since the entire program is written in JavaScript. The software runs on current iterations of macOS as well as Windows and Linux operating systems.

Well, at least from one of its creators.įelix Rieseberg, a senior staff engineer at Slack, has developed an app that emulates Mac OS 8. Those were the days: Have you ever found yourself missing the old Macintosh days? There's an app for that, and it comes from the most unlikely source-Slack.
