The Wild and Wonderful World of Early Microprocessors with a Focus on 6502
Explores the architecture and assembly programming of vintage 8-bit microprocessors, focusing on the MOS 6502 and retrocomputing platforms.
Summary
The Dawn of Microprocessor Computing
In the 1970s and 1980s, early microprocessors such as the Z80, MOS 6502, 6809, and 68000 launched the personal computing revolution, powering iconic systems like the Apple II, Commodore 64, and Atari 8-bit computers.
MOS 6502 Architectural Fundamentals
The MOS 6502 stood out for its low production cost, streamlined instruction set, and efficient zero-page addressing modes, making it a favorite for hobbyists and embedded engineers.
Programming in 8-Bit Assembly
Writing assembly code directly for the 6502 reveals foundational hardware interactions, memory management constraints, and hardware register manipulation that remain relevant to modern embedded systems.
Modern Retrocomputing and Hardware Building
Hacker communities continue to build new custom hardware, develop modern software, and reverse engineer classic architectures using vintage 6502 microprocessor designs.
