Getting Started with ASMz80: A Beginner’s Guide is a roadmap for programming the Zilog Z80 8-bit microprocessor using assembly language. This guide serves retrocomputing hobbyists, game developers for legacy systems (like the ZX Spectrum, Amstrad CPC, or MSX), and students trying to understand low-level computer architecture. 1. Understanding the Core Hardware Before writing code, a beginner must learn how the Go to product viewer dialog for this item. manipulates data:
Registers: These are small, ultra-fast internal storage units within the CPU. The A register (Accumulator) handles most math and logic. Other 8-bit registers include B, C, D, E, H, and L.
Register Pairs: Registers can combine to handle 16-bit data or memory addresses, such as BC, DE, and HL. The HL pair acts exactly like a pointer in higher-level languages.
Number Systems: Assembly requires jumping between Decimal (Base 10), Hexadecimal (Base 16, marked with an h suffix or $ prefix), and Binary (Base 2, marked with a b suffix). 2. Setting Up Your Development Environment
You do not need an actual 1980s computer to get started; modern cross-assemblers and emulators handle the heavy lifting: Getting Started With Asm – z80 Heaven – Wikidot
