Code, controversy, and popcorn
The IRIX 6.5.7M (sgi) source code
Vintage SGI code suddenly appears—nostalgia erupts, legality questioned
TLDR: A GitHub repo claims to host IRIX 6.5.7M’s source code, sparking a frenzy of nostalgia and legal worries. The crowd is split between “open‑source it already” and “this looks copyright‑sketchy,” with extra buzz around third‑party licenses and a handy emulator link for curious retro fans.
A mysterious GitHub repo claiming the source code for IRIX 6.5.7M—the colorful 90s operating system from Silicon Graphics (SGI)—just dropped, and the internet grabbed popcorn. Some users are screaming “Is this real?”, while others are loudly asking “Isn’t this violating copyright?” The repo’s glitchy “Uh oh!” load errors only added to the chaos, as if the page itself were teasing a forbidden treasure.
The hottest argument: should Hewlett Packard Enterprise (HPE)—which now owns the rights—just open‑source the whole thing? One commenter says it “can’t be worth much” anymore, while another warns that licensed third‑party bits might be the handbrake (cue comparisons to Opera’s unreleasable “Presto” engine). Meanwhile, the nostalgia floodgates opened: fans praised IRIX’s wildly colorful, beautiful GUI, and a helpful soul dropped a guide to run newer IRIX in the MAME emulator for curious time travelers: sgi.neocities.org. For context: IRIX was SGI’s star workstation OS for graphics and movies; AIX (another commenter’s crush) is IBM’s Unix; MAME emulates old machines so you can see vintage systems come alive.
So we’ve got a perfect internet cocktail: retro tech romance, copyright panic, corporate lore, and a dash of “lost code” myth. Is it legit? Is it legal? Either way, the comments are the main event—and they’re spicy.
