I've decided to develop a rough TL from my whole 'Different computer Industry' stuff.
There's multiple small PODs, but the primary ones are...
1984:
1. The IBM PCjr comes out with a slightly better keyboard and is priced just a touch better. It becomes a success (albeit a modest one), rather than a failure. With The PC, PC/XT, PC/AT, and PCjr all selling at least decently, IBM's Personal Computer business and its more 'unorthodox' tactics begin to dominate IBM, allowing them to be somewhat more competitive.
2. Apple's Macintosh is somewhat less successful, While it still makes a little money, it sells fewer units and is widely seen as being 'overblown'. OTOH, it still has enough of an effect to galvanize the process of GUI production.
1985:
3. Don Estridge, one of the important members of the PC development team, and who in no small part was responsible for the PC's success, doesn't die in a plane crash. Instead, he continues at IBM.
1985-6:
4. OS/2 is developed rather more competently than OTL. Its internals are slightly better, it comes with a built-in GUI (an upgraded MS-DOS Executive AKA Windows 1.0), and soon after its introduction a dedicated 386 version ('OS/2-386 1.1') is released - which can take full advantage of 8086 emulation and multitask MS-DOS Applications in a way that OS/2 versions prior to 2 really couldn't. OS/2-386 is far more successful than its 286-variant, and later OS/2s are developed mainly for the 386 processor, with MS-DOS 3.x and 4.x taking up the 8086 and 80286 market.
1986-7:
5. Motorola manages to solve problems with its 88000 series RISC processors earlier than it did OTL. This, in part, is responsible for RISC processors eventually becoming dominant, with PCs shifting over to Intel's "Pentium" series in the 1990s.
Some previews:
1. Major PC manufacturers include IBM, Epson, Compaq, HP, Apple, Dell, Gateway, TeleVideo, and Victor.
2. No anti-trust suit is brought against Microsoft, in part because Internet Explorer never exists, and in part because OS/2 and OS/3 never get more than 80-85% of the market, competing with, among others, AmigaOS and ClarisStep as well as the Unixen (from AIX to Solaris to Linux) and Planninen, plus BeOS in a few specialized systems.
3. The 'dynamic duo' of powerful non-PC manufacturers are Commodore and Acorn.
4. Nintendo, Sega, Atari, and Microsoft (and possibly even Apple?) are all making video game systems in the 2000s. No Sony Playstations, though.
5. ClarisStep is vaguely similar to Mac OS X but with an even more convoluted development path - its NeXTStep merged with ClarisOS, which in and of itself is kissing cousins both to MacOS and MS-DOS (for reasons which I'll go into later...).
