In This Issue

Hard copy was once considered a luxury by computer hobbyists, but now the ability to record program listings and text on paper is seen as almost a necessity. And though you're not likely to find a printer like the one Robert Tinney pictured on this month's cover, you're sure to find one from the many available that will fit your needs. For a rundown on what's around, see Curtis Feigel's printer directory. For a look at a new approach to printers, see Ed Umlor's review of the Prism Printer. We've also included a report on custom and standardized forms: where to get them and how to use them. And we have an article on programming your computer to fill in forms.

The Atari Tutorial continues with Part 7: Sound; William Barden Jr. discusses building a half-year clock for the Color Computer in the fourth article in his series on Radio Shack computers; in Part 2 of the "Input/Output Primer" Steve Leibson discusses interrupts and direct memory access; and Steve Ciarcia writes about using voiceprints to analyze speech. Don't miss our quarterly games feature, "BYTE's Arcade," plus our regular items and reviews.
