With this book you are provided with real, tested interfacing circuits
that work, plus the necessary software (in BASIC) to connect your Apple
computer to the outside world. This combination will enable you to: (1)
control electronic and electromechanical devices; (2) monitor external
events-temperature, pressure, liquid level, light level, etc; and (3) communicate
with other computers, modems, serial printers, and other interface devices.
First you are given the building blocks required for a thorough understanding
of interfacing. Clearly and concisely the authors take you through the
6502 microprocessor, Apple interfacing, input/output interfacing (input
ports and output ports), and flags. Breadboarding with the Apple, including
breadboard construction and connections to the Apple, is discussed. The
sixteen experiments in Chapter 6 tie everything together. Your comprehension
is continually reinforced as you connect the circuits, enter the commands,
and see the results. A communications interface (and software) as well
as a list of the interface signals available at the seven slots is given
in Chapter 7. Any Apple user who desires an extension of his computing
capabilities will find this book a valuable addition to his library. |
