IBM

The PC architecture that escaped its inventor and became an industry standard.

The museum thread

Why this brand matters

IBM's decisive contribution to the personal-computer story was not a uniquely exotic machine but a sufficiently open, documentable and reproducible platform. The 5150 PC and 5160 XT created a hardware/software target that clone makers could reproduce, eventually separating the 'IBM-compatible PC' from IBM itself.

The surrounding IBM systems show the platform evolving from an 8088 desktop into AT-class 286 machines, PS/2 buses and VGA, and eventually ThinkPads — while compatibility increasingly belonged to the wider industry rather than to one manufacturer.

Major machines and families

IBM in context

Brand histories overlap: CPUs, operating systems, standards, classroom adoption and software ecosystems routinely crossed manufacturer boundaries.
