New product applications: Microcomputer system includes processor, memory, interface, and modem

The MC6800, 8-bit microprocessor unit (MPU) is being made available with supporting components including a 128-by 8-bit random access memory (RAM), a 1024- by 8-bit read-only memory (ROM), a peripheral interface adapter (PIA), and a single-chip 0–600 bps modem. All these components are TTL compatible, MOS n-channel, silicon gate devices, and only a single, 5.0-volt supply is needed for all the devices. The system uses a single bus organization that allows memory and interface devices to share the same address space. All MPU and system bus control functions are available on separate, TTL level pins, and no multiplexing or decoding is required for operation; interfacing is accomplished without additional TTL parts.
