Open the cabinets in UC Davis computer science professor Dick Walters' office and you'll see how far computer technology has really come. The collection includes a computer much like the one on which Microsoft magnate Bill Gates got his start, as well as some predecessors of the modern-day laptop. From 10 a.m. to 3 p.m. on Thursday, May 23, several of the computers in the collection will be housed temporarily in Freeborn Hall as part of an exhibit for the campus technology showcase Odyssey '96. Odyssey '96 will vividly illustrate how technology is changing the university. Other invitations to visitors: see how music students use the keyboard -- make that the computer keyboard -- to study great composers; rotate a DNA molecule while using an interactive learning program designed to help medical students apply scientific information to real-life situations; and look for jobs and student internships on the World Wide Web using a special program created by the UC Davis Internship and Career Center.
