• 📦 Intel's 1103 in 1970 was the first DRAM chip, and IBM invented the floppy disk in 1971 for data sharing between computers.
• 💼 The Altair 8800 in 1975, using BASIC language, is credited with popularizing the term 'personal computer'.
• 🍎 Apple's entry in 1976 with the Apple I and subsequent Apple II in 1977 marked significant milestones in personal computing.
• 💾 The IBM PC in 1981, based on the Intel 8088 microprocessor and MS-DOS, revolutionized the development of personal computers.
• 🖥️ Apple Lisa in 1983 introduced the first graphical user interface in a personal computer.
• 🖱️ The Macintosh in 1984 was the first successful computer with a graphical user interface and a mouse.
• 🛠️ Michael Dell founded PC's Limited in 1984, developing the Turbo PC and becoming a leading computer developer in the 1990s.
• 📦 The IBM Personal System 2 in 1987 was the first IBM system with the Intel 80386 chip and OS2, introducing the mouse to IBM computers.
• 🌈 Apple's iMac G3 in 1998 featured a clear, customizable case and came with advanced specifications for its time.
• 🔌 The Apple G5 in 2003 was the first true 64-bit personal computer with an anodized aluminum case.
• 🌐 The 1990s saw the widespread use of personal computers with the advent of the Internet, leading to a growing market for computer components.
• 📚 The evolution of computers has been drastic, from room-sized machines to small, high-performance PCs like the Apple Mac mini.
