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.

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.
