Enhancing Your Apple II
Enhancing Your Apple II may sound like another general introduction to the world of peripherals, but beneath this nondescript title lies a wealth of information for hardware tinkerers and programming enthusiasts. This is a roll-up-your sleeves, hands-on tutorial on improving the performance of your Apple II+, IIe, or Franklin Ace computer and assembly language programs.
Using inexpensive components, Lancaster shows you how to interconnect various chips to modify field synch, flawlessly switch to and from lores graphics, and use video changeover switches with an RF modulator. On the software side, Lancaster leads you into mixing lo-res graphics, hi-res graphics, and text on the screen, cracking machine language code, creating 191 solid background colors, and gently scrolling images.
If this sounds interesting, you may also want to buy the companion disk of 26 programs, for $19.95.
