LGR looks at the Silicon Graphics Indigo2, a UNIX workstation that cost about $86,000 in 1995, covering its pros and cons, games it can run, and whether it is worth owning today.

A demonstration of loading Altair 4K BASIC on an Altair 8800 clone, using a front-panel bootloader and an ASR-33 Teletype. It shows the full sequence of entering boot code, loading BASIC and running a program.

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.

The original Amiga Boing Ball demo, written at the Winter CES in January 1984 to show off the Amiga's hardware, with a bouncing, spinning checkered ball running while the system multitasked. It became the Amiga's unofficial emblem.

A 1971 DEC LAB-8/e (PDP-8/e) minicomputer plays music by inducing noise into a nearby AM radio. The software is Richard Wilson's 1975 Music Compiler running under OS/8.

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 demonstration of the MONIAC, Bill Phillips' hydro-mechanical economic computer, at the Reserve Bank of New Zealand museum. It shows how water flows model an economy's money flows.
