Commodore 64 Programmer's Reference Guide

The Commodore 64 Programmer’s Reference Guide is the definitive technical manual for anyone who wants to program the legendary Commodore 64 on a deeper level. Originally released by Commodore itself, this book goes far beyond BASIC tutorials and provides a complete reference to the hardware and system architecture of the C64.

Inside you will find detailed explanations of the 6510 CPU, memory map, zero page usage, interrupts, and I/O addressing, along with an in-depth description of the VIC-II graphics chip, SID sound chip, and CIA interface adapters. The guide includes extensive tables, registers, memory locations, and examples that are essential for writing efficient machine language and low-level routines.

Whether you are a retro enthusiast, demoscener, game developer, emulator author, or electronics hobbyist, this book serves as an indispensable companion. It is not a "learn to program" book, but a serious reference manual – perfect for keeping close at hand while coding, debugging, or exploring how the Commodore 64 truly works under the hood.

A timeless resource that is as relevant today for retro-computer projects as it was in the golden age of 8-bit computing, remastered by Pickled Light.
