Welcome to our annual language issue. This year we present Logo, the microcomputer language perhaps best known for its turtle graphics. Mathematically minded readers may recognize the cover illustration by Robert Tinney as BYTE's own version (influenced slightly by M.C. Escher) of the classic four-bug puzzle. In this puzzle, for which a Logo program is shown on the cover, four bugs are placed at each corner of a square; each bug attempts to walk toward the bug to its immediate right. In the process they trace Archimedean spirals. The object is to calculate the length of the spirals. The answer: each is equal to the length of one side of the original square. But Logo is more than turtles, and our articles will tell you what it's all about.
To get you started, Harold Abelson presents "A Beginner s Guide to Logo," Brian Harvey answers the question "Why Logo?," and E. Paul Goldenberg fills you in on the jargon with "Logo-A Cultural Glossary." Daniel Watt discusses "Logo in the Schools," and Cynthia Solomon describes "Introducing Logo to Children." R. W. Lawler explains one of the unique abilities of Logo in "Designing Computer-Based Microworlds."
Steve Ciarcia shows you how to build a graphics board for your Apple II computer using the Texas Instruments TM59918A, and William Barden Jr. designs "A General-Purpose I/O Board for the TRS-80 Models I and III." Of course, we have Jerry Pournelle's User's Column and more.
