The Logic Analyser was purchased by the Ballarat College of Advanced Education Physics Department in the early 1980s. At the time it was a state of the art piece of test equipment used for fault finding and programming diagnostics for 8 bit computers. It was later used by the Electrical Engineers, after Physics merged with Engineering in the mid 1990s. The device monitored the 16 bit Address buss and 8 bit Data buss of an 8 bit computer. This device continually samples the 24 bits simultaneously and looks for a preset pattern. When the pattern is matched the logic analyser continues for a set number of steps thus allowing an operator to examine the data and address information both leading up to and after an event. This was particularly useful for diagnosing unusual programming and hardware errors. Logic analyzers are used in debugging and troubleshooting in mini- and microcomputers. The HP analyzers collect information through 24 (1615A) or 32 (1610B) inputs leads, connected to the computer's address, data and/or control lines. The logic state flow is shown on a display in a number of traces, a single data line or an appropriate combination of data lines providing a trigger signal. Captured data can be stored for detailed analysis. (http://http://www.science.uva.nl/museum/hp1610.php)Grey Analog computer. Includes keys and small screen.computer, logic analyzer, physics

Victorian Institute of Occupational Safety and Health (VIOSH) Australia is the Asia-Pacific centre for teaching and research in occupational health and safety (OHS) and is known as one of Australia's leaders on the field. VIOSH has a global reputation for its innovative approach within the field of OHS management. VIOSH had its first intake of students in 1979. At that time the Institution was known as the Ballarat College of Advanced Education. In 1990 it became known as Ballarat University College, then in 1994 as University of Ballarat. It was 2014 that it became Federation University. VIOSH Australia students are safety managers, senior advisors and experienced OHS professionals. They come from all over Australia and industry. Students are taught active research and enquiry; rather than textbook learning and a one-size fits all approach. VIOSH accepts people into the Graduate Diploma of Occupational Hazard Management who have no undergraduate degree - on the basis of extensive work experience and knowledge.
