Abstract
Prototyping of a computer system has not typically been a course taken by many systems analysts. The advantages and disadvantages indicate that a more efficient system with a better fit results when prototyping is used. Typically problems emerge as system development progresses. Prototyping allows for early analysis of the problems and facilitates the integration of their solutions into the final system. The mutual learning of user and analyst while prototyping diminishes communication problems.

Abstract
A data processing department should select software that is designed for its particular needs. The selection of software can determine the productivity of the department. An integrated software system should be selected that provides the following: easy-to-use applications for different levels of users, components that work well together, adaptability to both simple and complex situations. The software should provide for user-system interface through features such as menus that guide a user through the necessary operating steps, prototyping that allows a user to test the program, and step level refinement that enables simple corrections or changes. The correct software can result in increased productivity without the addition of staff or hardware.

Abstract
According to Merle Parks, product manager for Cincom, DP personnel need to recognize the following myths when developing applications: users' needs are static, users know what they want and users can communicate their needs to DP. When dealing with users, the system developer should illustrate several types of systems via menus. A photograph of Merle Parks is included.
Not many people build their own home computers from scratch anymore. However, one way to enchance any computer is to add on peripheral devices. To do this, one needs to understand how to put information in and get information out of the computer. In other words, one needs to understand an I-O prototype system. The included tables explain I-O theory. The included schematic diagrams show proper line connections. The listed programs allow for testing several I-O functions.

Relational Data Base Management Systems, DBMS, Mainframe Computer, Interface, Enhancements, and System 2000 Release 11 (data base management system)
Abstract
Intel's Release 11 of its System 2000 data base management system (DBMS) features relational DBMS functions, data base modeling, prototyping, decision assist for what-if analysis, and access to multiple data bases. Designed for IBM-based OS and VM-CMS environments, the package also offers a new teleprocessing interface that combines the attributes of the existing batch and TP interfaces. It sells for $70,000.

Abstract
The ADASI unit provides status information on all lines connecting an Apple computer to a floppy drive. Data Lok provides software protection for the Apple. An electromagnetic digitalizing tablet has been introduced by Numonics. Soundtrays lowers the noise level of most popular printers. Compact turns the Commodore 4032, 8032, and 64 into a communications control center. Micro 68000 is a portable training-prototyping system for engineers and technicians. The Wizard-EBI Epson Buffered Interface allows Epson MX Series printers to dump print data into the buffer quickly to free the computer. Pictures of these new products are provided.

Abstract
The use of a prototype to aid in determining system requirements is discussed. The idea behind prototyping is to provide a tool upon which specifications can be determined for the full blown system. User-analyst communication is facilitated because an actual model of the final system is the basis of discussions. Two problems are associated with prototyping. The first is the high expense of the requirements phase of the project and the second is that it is difficult to keep the requirements and design phase separate.
