Title: NDT-COMP9 microcomputer

Technical Report ·
DOI:https://doi.org/10.2172/5001537· OSTI ID:5001537

An 8080-based microcomputer system, the NDT-COMP9, has been designed for instrumentation control and data analysis in eddy-current tests. The NDT-COMP9 represents a significantly more powerful computer system than the NDT-COMP8 microcomputer from which it was developed. The NDT-COMP9 system is contained on a 240- by 120-mm (9.5- by 4.8-in.) circuit board and will fit in a four-wide Nuclear Instrumentation Module (NIM) BIN with 26-pin edge connectors. In addition to the 8080-compatible central processing unit (CPU), an arithmetic processing unit (APU) is available to provide up to 32-bit fixed- or floating-point, basic or transcendental math functions. The 16K of read only memory (ROM) and random access memory (RAM), one serial input-output (I/O) port (RS-232-C at a maximum speed of 9600 baud), and 72 parallel I/O ports are available. The baud rate is under software control. A system monitor and math package are available for use with the microcomputer.
