Sophisticated new operating systems and multitasking software promise to alter significantly the way we use personal computers. Because of the farge memory requirements of the new software, we're sure to see changes for the better in the nature of external storage devices. New technologies for mass storage will become even more critical as the software revolution continues to escalate. As Robert Tinney's cover suggests, personal computers will need a large quantity of high-speed mass storage to hold all the software and other data that we'll generate. Our theme articles address the latest developments in mass storage. Clark E. Johnson Jr. discusses "The Promise of Perpendicular Magnetic Recording;" Tom Moran looks at "New Developments in Floppy Disks," Edward Rothchild writes about "Optical-Memory Media," Larry Sarisky explores the question "Will Removable Hard Disks Replace the Floppy?" Jim Toreson concentrates on "The Winchester Odyssey," and in the first of a three-part series Andrew C. Cruce and Scott A Alexander discuss "Building a Hard-Disk Interface for an S-100 Bus System." Plus we have part 2 of "NAPLPS, A New Standard for Text and Graphics," the second installment in the VIC-20 series, "Adding a 3K-Byte Memory Board," a review of MP/M II from Digital Research, and BYTE's Game Grid. Steve Ciarcia tells you how to "Build the ECM-103, an Originate/Answer Modem," and more.
