Ebook: The Commodore 64 kernal and hardware revealed

A knowledge of the Commodore 64 kernal software and the
hardware with which it interacts is essential for programmers
wishing to make full use of the machine's capabilities. The
kernal software provides the interface between the user, the
BASIC interpreter and the electronics - and a thorough
knowledge of its functioning gives the programmer a wealth of
ideas and methods for interesting programming techniques.

This book gives the programmer a unique insight into the
operation of the Commodore 64 plus a wide variety of very
useful hints on subjects as diverse as reconfiguring the keyboard
and anti tape-copying security. The book also covers the user
port and the addition of external circuitry to it.
