EMMY system peripherals: principles of operation. Technical note No. 77

Technical Report ·
OSTI ID:7189575
Bus system peripheral units currently available in the EMMY laboratory are discussed from a functional point of view. The Main Memory System 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. The Datapoint Interface 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. The Maintenance Console 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. 11 figures.
