Michael MJD also published a video about @haiku|‘s successor #BeOS. You really need a #retromachine to use that. It also has a 2k11/time bug where you can get past the year 2010. That was new to me. Despite that it is quite astonishing how responsive this old #OperatingSystem runs on old hardware. If you’re interested, try #HaikuOS.
