IBM's entry into the small-computer market with its Personal Computer was a ·big event in the industry. And that's why we've taken a second look. Showcased in our cover photo by Paul Avis, the IBM Personal Computer is a versatile machine. For an in-depth report on its many features and capabilities read Gregg Williams' article, "A Closer Look at the IBM Personal Computer."
Hardware is our theme this month and among the many articles on that topic are Bill Barden's second in a series, "Build a Joystick A-to-D Converter for the TRS-80 Model I or III," and Kenneth Piggott's "Troubleshooting with Electronic Signatures." As well, learn how to expand your ZX-80's memory, control motors and appliances, and interrupt your Elf. All this plus our regular features and reviews.
