"...Open standards
The IBM team developed the PC in about a year,[4][31] and although the company denied doing so, many observers later concluded that IBM intentionally emulated Apple.[39] The many Apple II owners on the team influenced its decision to design the computer with an open architecture[36] and publish technical information so others could build expansion slot peripherals..."

"...Rather than trying to redefine the microcomputer, IBM would instead rely upon existing, proven technology to produce a competent, well backed, machine. This decision would also help to speed up the design process and allow for a very rapid build-up of production. Along with this path came the decision to purchase as many parts and sub-assemblies of the computer from outside companies as was feasible--again, this saved time, expense, and capital outlay. (Inside IBM's Entry Systems Division, they claim that every manufacturing step is preceded by a "Make or Buy" economic analysis.)

It was also decided along the way that the machine would have an "open" architecture, like that of the Apple family. IBM would include slots under the cover of the machine that could accommodate plug-in boards that would add features or even change the entire personality of the PC. And, to make it relatively easy for outside companies to participate in the building of the PC market, IBM would publish a Technical Reference Manual with the entire set of electrical schematics for the machine and a full explanation and printout of the ROM-based BIOS (Basic input Output System) that provides the hooks into the machine for hardware and software. The ROM BIOS and the IBM logo were actually the only elements of the entire machine that bore an IBM copyright.
