Black box: it's simple, it's unseen, it's crucial

Article Abstract:

'Back up your hard disk' is perhaps the most important reminder a microcomputer user could use. The hard disk drive, though generally ignored because it is usually unseen, holds all the data that a user has entered. If it fails to function or loses its memory, the computer is incapacitated and massive amounts of work done on the computer can be lost. It is imperative, therefore, to take care of the hard disk and its data regularly. New software, such as WordPerfect for Windows, require a hard disk capacity of 40Mbytes or higher. If a user intends to take advantage of various Windows applications, it would be necessary to consider hard disks with a capacity of 80Mbytes or more. Among the options available for users who need more hard disk space are: adding a new hard disk on a card, such as Plus Development Corp's Hardcard II; conserving hard disk space through the use of integrated software packages, such as Microsoft Works or Lotus Works; and using compression software, such as Stac Electronics' $149 Stacker, to compress regular programs into a fraction of their normal space.

Making a Mac more like a work station

Article Abstract:

Radius Inc offers a plug-in card called the Rocket ($3,495) that can increase a Macintosh II microcomputer's performance to the level of a high-performance workstation. The Radius Rocket coprocessor board, which adds a 25-MHz Motorola 68040 microprocessor to a Mac, will be especially appealing to users who work with large color images or other complex graphics. Plugging a Radius Rocket into a Mac II, IIx or IIcx yields a computer that outperforms an Apple Mac IIfx, which is Apple's top-of-the-line machine. An Apple Mac IIfx uses the older Motorola 68030 chip. According to Radius, the Rocket will increase performance of a Mac II to a sustained rate of 20 million instructions per second (MIPS), which compares with computer systems that cost 10 times as much. Mac II owners may find the Radius Rocket upgrade to be an attractive alternative to Apple's own 68040-based 'tower configuration,' expected later in 1991.

New models establish a milestone in printers

Article Abstract:

Hewlett-Packard's introduction of a low-cost laser printer represents a price breakthrough for the products. HP's Laserjet IIP, priced at $1,495, is the first to be priced at under $1,500 and is expected to be sold on the street for as little as $1,000. Toshiba America Inc and Seiko Epson Corp have both recently introduced laser printers which are expected to be discounted to around $1,400. IBM is developing low-cost laser printers in the $1,300 range. The new printers are comparatively small and light and, though capable of producing professional-looking documents, they lack the speed and many of the features of higher-priced models.
