All About Electronic Spreadsheets

Article Abstract:

First generation electronic spreadsheets, such as VisiCalc, while limited to single applications, are good for introducing the concept. The second generation, such as Lotus 1-2-3, integrates graphics and database management into its modeling applications. Lotus is compatible with twelve computer makes. Context MBA is basically a database program which incorporates spreadsheet, word processing and graphics capabilities. One command language is used for all applications. Telecommunications and windowing are additional features. Third generation spreadsheets are described as operating environments. VisiOn's Application Manager directs the integration of VisiOn Calc, VisiOn Graph, VisiOn Word, and VisiOn Query. The Desq system, an operating environment due January, 1984, integrates any applications programs in MS-DOS 2.00 for the IBM PC or PC XT. The Mark and Transfer feature takes information from one application and transfers it into another. Desq requires a five megabyte hard disk and preferably 512K of memory. A screen display of VisiOn is shown. A spreadsheet vendor lisitng is included.

Electronic Circuit Lock Stands Between Thieves and Microprocessor-Controlled Devices

Article Abstract:

The new Kaish Circuit Lockout system will eliminate the profit involved with resale of stolen microprocessor-controlled devices. The equipment will not operate if tampered with or unplugged. The system has three digitial codes, one of which is programmed by the owner, and can be changed at will. It would take 34,000 years for a large IBM computer to compute the one trillion possible code combinations.
