Why This Matters

The Virtual OS Museum is a groundbreaking project that preserves and provides access to a vast archive of over 600 operating systems spanning from 1948 to today. It offers enthusiasts, developers, and historians a unique opportunity to explore the evolution of computing through emulated environments, fostering a deeper understanding of technological progress and legacy systems. This initiative highlights the importance of digital preservation and accessibility in the rapidly evolving tech industry.

Key Takeaways

If you’ve ever wondered what it felt like to use the many operating systems Apple (and NeXT) released over the past 40-plus years, The Virtual OS Museum has got you covered, and then some. Here are the details.

’Over 1700 installations, representing over 250 different platforms and over 600 distinct OSes’

As spotted by BoingBoing, The Virtual OS Museum is a project by developer Andrew Warkentin, which offers a way to run more than 1,700 pre-installed operating systems and standalone applications under emulation, covering more than 250 platforms and roughly 600 distinct operating systems from 1948 to the present.

The project is available in two editions: a full 121GB download (174GB unzipped), with everything pre-downloaded for offline use, and a lighter 14GB download (21GB unzipped), which downloads guest VM images the first time they are run.

Or, as The Virtual OS Museum puts it:

Both a full and a lite version are available. The full version ships with everything pre-downloaded and runs offline. The lite version downloads disk/tape/etc. images for guest VMs the first time they are run. Automatic and manual updates are supported on both editions so new installations land without re-downloading the whole VM.

Warkentin says that The Virtual OS Museum “is the result of over 20 years of collecting, which began as he started collecting emulator images in 2003, a time when there were only a few small archives of software images and documentation available.

Here’s some of what you can expect to find:

The earliest mainframes : Manchester Baby test/demo programs, Mark 1 Scheme A/B/C/T (the earliest examples of system software that could be considered as an OS), various EDSAC software, etc.
