🕰 2. Part I: 1970s–1980s – The Dawn of the Personal Computer

2.1 Altair 8800: Birth of the Hobbyist Revolution

• Released: 1975
• Specs: Intel 8080 CPU, 256 bytes RAM (!)
• Programming method: Front panel switches
• Legacy: Inspired Bill Gates and Paul Allen to form Microsoft

📦 “There was no screen. No keyboard. Just binary lights and switches.”

2.2 Apple II, Commodore 64, IBM PC

Computer	Year	RAM	OS	Impact
Apple II	1977	4KB–48KB	BASIC	Brought color and gaming
Commodore 64	1982	64KB	BASIC	Best-selling PC ever
IBM PC	1981	16KB–256KB	PC-DOS	Defined “IBM-compatible” era

2.3 Software: MS-DOS, WordStar, and BASIC

By the end of the 1980s, most home computers ran some form of command-line interface, with floppy disks ruling the data world.
