IBM PC 1981


IBM released their Personal Computer named PC, with the IBM model number 5150 produced from August 12 1981 to April 2 1987. This spawned various clones and for young guys, that is why you see "IBM Compatible" on hardware today.



One thing IBM did at the time is that they published for a fee a technical document that not only allowed clone makes quick reverse engineering of the PC but allow a standard open system development in a world were many incompatible standards existed.

The ZIP files listed below (that I am posting as a educational reference for others to learn more about early computers) are a gold mine of information, that if someone wanted to they could produce a new PC today with ease. Just goes to show that IBM was dedicated to its customer base that they effectively gave away big money R&D to standardize the PC market.

My personal theory right or wrong is that IBM never wanted the PC market, they did what they did to standardize the market. Which would allow them to develop and support their core business of serving their corporate clients much more effectively if they only need to worry about one client side standard instead of many.
