Sun Microsystems Inc has signed up Toshiba Corp, one of its system relellers in Japan, to build its forthcoming low-cost Internet access terminal, US PC Week reports, saying Toshiba America Information Systems Inc confirmed the development. The paper also reports that Sun plans to have a thin and highly portable operating system dedicated to running Java applets on anything from low-cost handheld graphical terminals to television set-top boxes. The proprietary operating system is designed to take up very little memory, but has few services.
