The Virtual OS Museum is an epic collection of historically significant operating systems, representing more than 600 OSes across upwards of 250 platforms. It’s all local, so you’ll need a good few gigs of space.
The Virtual OS Museum is a giant mixtape for enthusiasts of the history of OS evolution. As an indication of its breadth of coverage, it reaches all the way back to the
Manchester Baby – from 1948. Multics, the Xerox Alto, NeXTstep, PowerPC Mac OS X, early versions of Windows NT and Android, and more.
It is one hefty layer-cake of code. The project offers
two versions to download. The Full edition is a whopping 121 GB download, which unpacks to 174 GB, but includes everything ready for offline use. If that’s a little indigestible, there’s also a “Lite” edition which includes the various emulators, but not the all the disk and tape images of actual vintage OSes: those are downloaded and run on first use. This is a mere 14 GB download, which expands to 21 GB of space.
