Co-wrote in 1987 with Dan Gookin, this 642-page monster reveals the secrets to programming the Apple IIGS, Apple’s last incarnation of the Apple II series. The IIGS combined the value of the venerable Apple II with the user-friendliness of the Mac. The GS stands for graphics and sound, cutting edge at the time, rivaling that of its Mac brethren for a while. (Trivia: The publisher sorted our hexadecimal toolbox function index in alphabetical order, making it a treat for programmers to follow.)
My dear friend and co-author, Dan Gookin
