Bus system peripheral units currently available in the EMMY laboratory are discussed from a functional point of view. Main Memory System -- This unit consists of a core memory system and an associated memory controller. The memory controller is designed to provide elementary data transformations useful in the emulation environment. Datapoint Interface -- This unit provides a means of communicating between the eight bit Datapoint 2200 bus system and the 32 bit EMMY bus. Direct status indication and control of the CPU are also available. Maintenance Console -- This unit provides the user with a direct display of the information being handled by the EMMY bus system. Information may be trapped and held for examination when a user select event occurs on the bus system.
