The book provides context for why "clones" exist. In 1981, IBM used "off-the-shelf" parts (like the Intel 8088 CPU) to build their PC. This allowed companies like and Columbia Data Products to reverse-engineer the BIOS and create 100% compatible machines that were often cheaper and faster. This "Clone Revolution" eventually broke IBM’s monopoly on the market and established the "IBM-compatible" standard we still use today. 4. Technical Breakdown of the Chapters
