Personal Computers: How Are They Used in the American Household
Fourth Floor Oklahoma State University Library PERSONAL COMPUTERS: HOW ARE THEY USED IN THE AMERICAN HOUSEHOLD by STANLEY KEITH WALTON Bachelor of Science Murray State University Murray, Kentucky 1978 Submitted to the Graduate Faculty of the Department of Management College of Business Administration Oklaho ma State University in partial fulfillment of the requirements for the Degree of MASTER OF BUSINESS ADMINISTRATION May, 1984 Name: Stanley Keith Walton Date of Degree: May, 1984 Institution: Oklahoma State University Location: Stillwater, Oklahoma Title of Study: PERSONAL COMPUTERS: HOW ARE THEY USED IN THE AM ERICAN HOUSEHOLD Pages in Study: 100 Candidate for Degree of Master of Business Administration Major Field: Business Administration Scope and Method of Study: This study developes a "post purchase usage survey" for households that own personal computers. The survey was designed, conducted, and analyzed over a period of two months. Additionally, an in-depth look was taken at the entire computer revolution, personal computers, and the changing role households are playing in the computer revolution. Findings and Conclusions: Personal computers used in the Ame rican Household have passed the stage of primarily being used by hobbyist or for only playing games. Home users are adapting a wide varie ty of applications to home computers. However, the American consumer, for the most part, is willing to give up leisure time for pr ogramming activities. But, the consumer is willing to purchase woftware which will provide a similar utility. Nevertheless, these findings have enforced this r esearcher's belief that personal computers in t he American home have become the norm. -

Who'd a Thunk

NICOLL, PhD, MBA, RN-BC Editor-in-Chief Beginning with this volume, CIN: Computers, Infor- matics, Nursing celebrates its 25th year of publication. When founding editor Gary Hales, PhD, penned the first words of his first editor’s comments, I wonder what he thought. Could he imagine what computers would look like 25 years later or that nurses would use them to map nursing concepts, educate students, or locate the latest evidence to incorporate in practice? Did he envision the Internet? Did he think that SPAM was just a canned meat product? (For the last question, the answer was probably yes.) I thought back to 1982 and tried to remember ‘‘then’’ and ‘‘now.’’ In 1982, I was married but didn’t have any FIGURE 2. Volume 2, number 2 of Computers in Nursing, March/ April 1984. children.

A 10 megabyte unit goes now for about $900. We're presently looking for 80 megabytes for less than $3000! The up-to-$600 for quarter megabyte of RAM is for a plug-in board, not the price of loose chips! (Thanks to Robert Heckert, Fullerton, California, for high1ighting potential misunder- standing caused by our phraseologies.) Our position, restated, is: very useful programs need use no more than 20 or 30 kilobytes of RAM, of Transient Program Area. Using overlays and chaining permit programs of any size to run fast, very fast, if a fast, correctly installed, Winchester is used for program-module storage. Such a philosophy means that BIOS or CP/M-system size is not of much importance. It seems there is some emotionalism involved in setting up ZCPR3 systems with, say only 48K TPA. (We always assume RAM to be full 64K-bytes.) Our experience suggests few CP/M programs need more than a 48K TPA. We have run both T/Maker and WordStar in 44K and, subjectively, can see no chance in operating speed caused by reduced buffer allocation space. Who wants to conduct measurements of time taken to scan files, run spreadsheets, etc., with various sizes of TPA? We'll report your findings here.
