Abstract
Over the past decade we have built a laboratory and research environment for the study of architectures and emulation. Initially most effort was directed at building the host processor, EMMY, and its support tools. The next stage was to emulate a variety of instruction sets --- building an archive of emulators. Now we have well over a dozen emulators and can add a new one quickly. A student can emulate a know image architecture in about ten weeks --- twenty weeks includes verification and documentation --- thirty weeks for I/O and interface to a simple operating system. (A student-week is about 6 - 8 hours of effort and corresponds to three units of credit.)
