The OS that ghosted its own party
OS/2 Warp, PowerPC Edition
IBM’s rare drop that ran on 90s Mac-style chips
TLDR: IBM launched a rare OS/2 Warp for PowerPC in 1995, supporting few machines and fading fast. Comments swing from surprise it existed to nostalgia and strategy debates—missed Power Mac ports and canceled OS/2+Mac dreams—highlighting how risky 90s platform bets reshaped today’s tech landscape.
IBM quietly “shipped” OS/2 Warp for PowerPC in 1995 like a limited-edition mixtape only a few insiders got. It ran on a tiny list of IBM machines, then vanished—no box, just pretty CDs—and the community is buzzing with nostalgia, disbelief, and armchair CEOing. Some readers only just learned both OS/2 (IBM’s would-be Windows rival) and Microsoft’s Windows NT had PowerPC versions, cue: "wait, that existed?" Meanwhile, the article’s throwback hardware tour screams collector’s vibes—S3 graphics, tiny hard drives, and the kind of compatibility roulette only the 90s could love. Read the backstory at the OS/2 Museum.
The hot takes are spicy. One camp mourns what could have been: tiahura daydreams about an alliance of OS/2, WordPerfect, Lotus, and the PPC 615 chip like a crossover episode that never aired. Dhosek remembers rumors of an OS/2 + MacOS dual-boot fantasy—"never to be"—and the crowd collectively sighs. Then come the pragmatists: nxobject asks why IBM chased a dead-end instead of porting to Power Mac, and wonders if x86 app emulation was even real. Nostalgia gets loud too: jmspring swears OS/2 (on Intel) “just worked” while they cranked builds at Netscape. It’s part love letter, part alternate timeline, all retro drama.
Key Points
- •IBM released OS/2 Warp, PowerPC edition in December 1995 with limited distribution and minimal marketing, ending OS/2’s PowerPC development.
- •OS/2 PPC supported only IBM’s Personal Power Series 830/850 desktops and likely ThinkPad Power Series 820/850, with narrowly defined hardware support.
- •The Power Series shared hardware lineage with RS/6000 (e.g., 43P-7248) and were intended to run OS/2, Windows NT, AIX, or Solaris; AIX support lasted through version 5.1.
- •Microsoft dropped Windows NT support for PowerPC in 1996 after NT 4.0; Solaris 2.5.1 for PowerPC was also short-lived; Linux had partial support.
- •Installation of OS/2 PPC was via a bootable CD across two discs (OS+BonusPak and an app sampler) and was straightforward with minimal user choices.
