Only peripherals (computer input/output devices terminals, printer, etc.) certified to comply with Class B limits may be attached to this computer. Operation with non-certified peripherals is likely to result in interference with radio and TV reception. NOTE: In order to meet Class B emission limits, the I/O cables that interconnect between this computer and any peripheral (such as a printer, external modem, etc.) must be shielded. This equipment generates and uses radio frequency energy for its operation and if not installed and used properly, that is, in strict accordance with the instruction manual, may cause interference with radio and television reception. It has been tested and found to comply with the RF emission limits for a Class B computing device which are intended to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference with radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Move the computing device away from the receiver being interfered with. • Relocate the computing device with respect to the receiver. • Reorient the receiving antenna. • Plug the computing device into a different AC outlet so that the computing device and receiver are on different branch circuits. • Be certain that the computing device is plugged into grounded outlet receptacles. Avoid using AC cheater plugs. Lifting of the power cord ground may increase RF emission levels and may also present a lethal shock hazard to the user. If you need additional help, consult your dealer or ask for assistance from the manufacturer. You may also find the following booklet helpful: How to Identify and Resolve Radio-TV Interference Problems. This booklet is available from the U.S. Government Printing Office, Washington D.C. 20402, Stock No. 004-000-00345-4. FCC regulations Part 68 places three restrictions on using the modem: 1. The modem cannot be connected to a party line or coin-operated telephone line. 2. You must notify the telephone company that the modem is being installed and provide the following information: modem registration number, ringer equivalence number, and telephone number to which the modem is connected. 3. Notify the telephone company if you have questions about the operation of your telephone line when connected to the modem.

Packard Bell Acquires Zenith Data Systems Page 1 Intel Introduces Fourth Generation Pentium Chip Sets Page 2 Memory Developments in the PC Market Page 3 Intel's Motherboard Operation's Semiconductor TAM Page 5 Dell Computer Corporation—Channels and Manufacturing Page 7 Packard Bell Acquires Zenith Data Systems Packard Bell, Groupe Bull and NEC have reached an agreement that gives Packard Bell control of the Bull subsidiary. Zenith Data Systems (ZDS). Under the agreement, NEC will contribute $283 million in new investment alongside Bull's transfer of ZDS, which is valued at $367 milUon. Groupe Bull and NEC will receive convertible preference shares in the combined organization, giv­ ing each 19.9 percent of the new company, just below the 20 percent level at which they would have to consolidate the new company's results in their own figures. Dataquest estimates that Packard Bell was the world's fourth-largest PC maker in 1995 and the second-largest behind Compaq in the United States. ZDS was the thirteenth-largest PC vendor in the world and fourteenth in the United States. Combining their shipments would still leave Packard Bell fourth in the world. It would, however, become the largest PC vendor in the United States. In Europe Packard Bell was seventh and ZDS was thirteenth. Combining the two w^ould result in them rising to fourth position after Compaq, IBM and Apple.

    Read the selection and choose the best answer to each question. Editing Laptops adapted from Simple English Wikipedia 1 (1) The first laptop was invented in 1979 by British Designer Bill Moggridge. (2) GRiD Systems Corporation helped improve his design. GRiD made the product with a fold-down display that covered the keyboard. (3) It was called the GriD Compass. (4) In 1982, Grid Systems began to make many GriD Compass laptops. (5) They were mostly sold to the US Military and NASA. 2 (6) GRiD’s computer was one-fifth the weight of any other computer used at that time. (7) NASA used the laptop in its Space Shuttle program, in the 1980s. (8) The Grid Compass required mains power (will not run on battery power). (9) GRiD owned patents for the “Clamshell” design, which is used in almost all modern laptop designs. (10) GRiD Systems was bought by Tandy Corporation in 1988. (11) Some historians, however, count the first “true” portable as the Osborne 1. (12) It was created in 1981 by Adam Osborne, who was also a former book publisher. (13) He was the founder of Osborne Computer. (14) His portable computer weighed 24 pounds (11 Kg). (15) The computer had a five-inch screen, a serial port and two floppy disk drives. (16) Several programs were included with the Osborne 1. (17) Customers could also buy a one-hour battery pack. 3 (18) Also in 1981, another laptop computer called Epson HX-20 went on sale. (19) It was a portable computer with a liquid crystal display (LCD) monitor.

  • Operators Manual Part 2
    Z-100 Manual Appendix A Page A-1 A Glossary of Commonly-Used Computer Terms This appendix is a short glossary of the commonly-used computer terms that you may encounter while working with the Z-1 00 Computer. Acoustic coupler (Modem) – One of the two types of modems: a device you can connect between a standard telephone handset and a computer to communicate with other computers. A modem will translate the normal digital signals of the computer into tones that are transmitted over standard telephone lines and will translate the received tones back into digital signals. By using an acoustic coupler modem, you can use any telephone with a standard handset on a temporary basis and avoid a permanent connection to the telephone lines. See Modem; and Direct-Connect Modem. Acronym – A word formed from letters found in a name, term, or phrase. For example, FORTRAN is formed from the words FORmula TRANslator, Address -- The label, name, or number identifying a register, location or unit where data is stored. In most cases, address refers to a location in computer memory. Algorithm – A defined set of instructions that will lead to the logical conclusion of a task. Alpha – The letters of the English alphabet. Alphanumeric -- Letters, numbers, punctuation, and symbols used to represent information or data. ALU – Arithmetic Logic Unit. This section of the computer performs the arithmetic, logical, and comparative functions of an operation. ANSI -- American National Standards Institute. This organization publishes standards used by many industries, including the computer industry. Most noted are those standards established for computer languages such as FORTRAN and COBOL.
