In the Fall of 1992, the graduate Operating Systems class at Carnegie Mellon University implemented the necessary components to provide applications with a programmable interface to a mobile palmtop computer. The goal of the project was to expose project members to the area of mobile computing through ``shock immersion.'' Over the course of two months, students designed and implemented the infrastructure for a simple mobile computing environment for low-end palmtop machines. This programming environment was used to develop a suite of mobile applications such as a mailer, graphical locator map, the game tetris, and a scheme interpreter that allowed functions to be remotely executed on the palmtop. In this paper, we describe the results of the course project and the lessons learned.
