Abstract This handbook introduces management and staff of small to medium sized transit agencies to the use of microcomputers in transit operations. It describes the types of computer programs of use in this industry, and documents applications of some common ones. The handbook is in two parts. Part I describes a process for identifying appropriate use of microcomputers, and introduces the various types of computer programs. Chapter 1 introduces the components of the microcomputer system. Chaptei 2 outlines a process for identifying worthwhile and feasible uses of a microcomputei in the agency, by reviewing the various tasks which are candidates for automation. The following 5 chapters introduce different types of programs by describing their use and things to look for in selecting a program. Chapter 3 discusses generic software, including spreadsheets, database managers and word processors. Chapter 4 describes application software, programs written to accomplish a particular task in the transit industry. Chapters 5, 6, and 7 concern operating systems, programming languages and utility programs respectively. Finally Chapter 8 discusses some considerations in introducing a microcomputer into the agency. Part II documents applications of generic programs, primarily spreadsheets, in the transit industry. Each application is illustrated, and documented with notes permitting reconstruction of the application by new users. This handbook is a companion document to Microcomputers in Transit: A Hardware Handbook. 17. Kay Wards 18. Distribution Statement microcomputers, transit operations, Availability is unlimited.

There are 405,535 employees and 798,152 stockholders at year-end. Organization IBM President John F. Akers succeeds John R. Opel as chief executive officer, effective February 1. Mr. Akers also is to head the Corporate Management Board and serve as chairman of its Policy Committee and Business Operations Committee. PC dealer sales, support and operations are transferred from the Entry Systems Division (ESD) to the National Distribution Division, while the marketing function for IBM’s Personal Computer continues to be an ESD responsibility. IBM announces in September a reorganization of its U.S. marketing operations. Under the realignment, to take effect on Jan. 1, 1986, the National Accounts Division, which markets IBM products to the company’s largest customers, and the National Marketing Division, which serves primarily medium-sized and small customer accounts, are reorganized into two geographic marketing divisions: The North-Central Marketing Division and the South-West Marketing Division. The National Distribution Division, which directs IBM’s marketing efforts through Product Centers, value-added remarketers, and authorized dealers, is to merge its distribution channels, personal computer dealer operations and systems supplies field sales forces into a single sales organization. The National Service Division is to realign its field service operations to be symmetrical with the new marketing organizations.

    Written by Published by Nick Tredennick DynamicSilicon Gilder Publishing, LLC Vol. 2, No. 9 The Investor's Guide to Breakthrough Micro Devices September 2002 Lessons From the PC he worldwide market for personal computers has grown to 135 million units annually. Personal com- puters represent half of the worldwide revenue for semiconductors. In July of this year, PC makers Tshipped their billionth PC. I trace the story of the personal computer (PC) from its beginning. The lessons from the PC apply to contemporary products such as switches, routers, network processors, microprocessors, and cell phones. The story doesn’t repeat exactly because semiconductor-process advances change the rules. PC beginnings Intel introduced the first commercial microprocessor in 1971. The first microprocessors were designed solely as cost-effective substitutes for numerous chips in bills of material. But it wasn’t long before micro- processors became central processing units in small computer systems. The first advertisement for a micro- processor-based computer appeared in March 1974. Soon, companies, such as Scelbi Computer Consulting, MITS, and IMSAI, offered kit computers. Apple Computer incorporated in January 1977 and introduced the Apple II computer in April. The Apple II came fully assembled, which, together with the invention of the spreadsheet, changed the personal computer from a kit hobby to a personal business machine. In 1981, IBM legitimized personal computers by introducing the IBM Personal Computer. Once endorsed by IBM, many businesses bought personal computers. Even though it came out in August, IBM sold 15,000 units that year. Apple had a four-year head start. When IBM debuted its personal computer, the Apple II dom- inated the market.
