Quick Summary

IBM PC clones, also known as IBM compatibles, are computers designed to be functionally identical to the IBM Personal Computer (PC). This compatibility was made possible by IBM's decision to use off-the-shelf components and an "open architecture". This allowed other companies, like Compaq Computer Corporation, to reverse-engineer IBM's technology and create "100 percent compatible" machines. These clones offered comparable functionality, often at competitive prices, and significantly broadened the personal computer market, impacting companies like Apple.123
