PC era: training wheels for desktop computing

Desktop computer systems have become familiar office fixtures since IBM's introduction of its PC over five years ago. Rapid computer hardware and software developments are anticipated through the remainder of the decade. Processor clock speeds are increasing. Coprocessor boosters can help improve screen resolution or increase graphics programs execution speeds. Hard disc memory capacities are increasing. Printers work faster, and at higher resolutions in more font styles. Items still needed include: operating system software to make running several programs as simple as running one, an operating system that will break the 640Kbyte memory limit, more complex expert systems, and 'shuttleware' that will translate text, images, data, and graphics from one device to another.
