THE BEST VIDEO TEXTBOOKS FOR PCs     

Back in 1987 Richard Wilton wrote the definitive video textbook for beginners and intermediates that thoroughly covered all the fundamental aspects of the PC's basic video system. It was truly a classic and titled "Programmer's Guide To PC & PS/2 Video Systems." It was published by the Microsoft Press for about $25. Its ISBN book number was 1-55165-103-9 and it went through so very many printings and its sequel by Richard Wilton that it became a classic. The thirteen chapters and three Appendices contents covered in 532 pages:

The contents of this book are so relevant that I wore out two copies of this book while doing nearly ten years of IBM Touchscreen Information Systems assembly language programming.  Unfortunately it is now out of print, but if you have a friend who has a copy and will loan it to you, by all means read and study it.

There is another book still in print that has been considerably updated from the one discussed above. It is titled: "Programmer's Guide to the EGA, VGA and Super VGA Cards" by Richard F. Ferraro with a monster 1,632 pages. Its ISBN number of its third edition is ISBN 0-201-62490-7 and may be available from your local bookstore. If not, you may order it from our favorite bookseller in Cedar Creek, Texas, ABYSS BOOKs. Toll free phone number is: (888) 999-2665 = (888) WWW-BOOK. Ask for my special friend Maria who is a computer books expert. You will receive a significant discount from the book's $44.95 list price.

Here is the detailed advertising/boiler plate on Richard Ferraro's 3rd edition.

"...I've found this book useful when I've reached for it, and I've found myself reaching for it increasingly often, and that's the real test of any reference."
- Michael Abrash, Dr. Dobb's Journal. NOTE: Michael is a GENIUS programmer

"A gold mine of information...." - PC Resource>

"You will find this a valuable reference source....It takes the place of detailed technical manuals that explain the theory of programming these devices, but which are not designed to teach the practice."
- Online Today

"This book provides essential tools urgently needed by graphics programmers. Now, the full potential of the Super VGAs can be realized."
- Bo Ericsson, Cirrus Logic Board Member, VESA Standards Committee

Programmer's Guide to the EGA, VGA and Super VGA Cards, Third Edition, is the most outstanding guide to industry graphics standards for personal computers. This classic reference gives readers the knowledge and skills they need for successful graphics programming. It explains the PC graphics environments and graphics programming principles and details the features and operation of the Super VGA, VGA, XGA, 8514/A and EGA graphics standards. The core of the book teaches readers how to write programs that support and take advantage of all of these standards and the most popular chip sets and graphics boards supporting these standards. The book features a set of extensive, protected-mode compatible and optimized code examples in C and assembly language that illustrate techniques for programming text, font, graphics, and color features of the major industry chip sets.

This thoroughly revised third edition of the Programmer's Guide focuses on the Super VGA standard that now dominates the industry. The book details programming parameters and techniques for the latest graphics cards in both completely revised and wholly new chapters. The Programmer's Guide also features entirely new coverage of:
