This paper describes a hot-stamping operation undertaken at Drexel University in an attempt to prevent computer theft on campus. The program was initiated in response to the University's anticipated receipt of up to 3,000 Macintosh microcomputers per year and the consequent publicity the university was receiving. All clusters of computers (e.g., communal work areas within departments, general student/faculty access areas, and print stations) were equipped with electronic security devices. However, because university-owned machines would account for only a small fraction of the Macintoshes on campus, and because it was believed students would probably not invest in a security device, an interim solution to "brand" each of the Macintoshes purchased through the university was implemented. A transformer plus a hot iron at the end of a drill press was used in the hot-stamping operation. This operation will, however, probably be discontinued because the incidence of computer theft on campus has been much lower than expected and the effectiveness of the stamp seems to be almost nil. At present, students are asked whether or not they wish to have their machines stamped and data will be kept to see if the unstamped machines turn out to be more vulnerable to theft than those with the stamp.
