We describe a development environment we created for prototyping software for the Macintosh. The programs are developed and executed on a large time-shared computer but can use the full facilities of the Macintosh. By using this system, we combine the advantages of the large system, such as large amounts of disk storage and automatic file backups, with the advantages of the Macintosh, such as advanced graphics, mouse control and sound synthesis. We also describe several projects that used the distributed development system. We conclude with a description of our future plans for this environment.
