The official demo video from Be, Inc. showing BeOS running multiple videos, media applications and a responsive desktop on 1990s hardware.

Andreas Kling ports the game Diablo to SerenityOS, his from-scratch Unix-like operating system, using the devilutionX project. The roughly 80-minute session shows what porting third-party software to the OS involves.

Steve Jobs demos NeXTSTEP Release 3, showing the object-oriented development environment and UI that later became the basis of Mac OS X. Midway through he builds a database-backed GUI app with Interface Builder and Enterprise Objects Framework with almost no code.

A demonstration of SymbOS, a multitasking operating system for 8-bit Z80 machines, running on a real MSX turboR with an MP3MSX card and a CF IDE interface. It shows the OS playing audio and running a graphical desktop on very old hardware, captured from the real machine and not an emulator.

TheRasteri installs MS-DOS and Windows 1.0, then upgrades in place through nearly every Windows version up to Windows 7, checking which programs survive. Even Doom from 1993 still runs at the end.

Solomon Hykes shows Docker to the public for the first time in a five-minute lightning talk at PyCon 2013. It demos Linux containers and the simplicity of a Dockerfile.

A short demo showing slow 2D drawing in the Windows 7 GUI compared with XP. It attributes the slowdown to the display driver model lacking hardware accelerated GDI.

A vintage demo video of the BeOS operating system running on mid-90s hardware. It shows media playback and window manipulation staying smooth at the same time.

A short demo of Inferno, the Plan 9 descendant operating system, running on an Android phone as Hellaphone. It shows calls, SMS and data working. The video quality is rough because the camera was held in front of the screen.

Eric Parker connects a fresh Windows XP machine to the internet in 2024 to see how quickly it gets infected with malware. He documents the dangers of running an unpatched legacy OS online.

A short demo of Sun Microsystems' Looking Glass, a 3D desktop GUI concept for a future operating system.

TheRasteri upgrades a single PC through every Windows version, from early releases through Windows 10, testing that old software keeps running. It is an updated version of the Chain of Fools experiment.

Enderman gets Windows 11 running on a Pentium 4 system with a Radeon HD 5870 and 8 GB of DDR2. It explores how an unsupported, ancient CPU can be made to work by using the rare last Pentium 4 variant and a registry flag.
