This computer was used originally by the Snowy Mountains Authority, probably on the Snowy Mountains Scheme. It required 10kW of power and had air draught on all rack cabinets. All valve operation, it was cumbersome and would have required a lot of maintenance. Eventually taken over by the CSIRO in the early 1960s, the Museum was offered the lot but the units were too heavy and would have occupied too much of our storage space. These units are of the more spectacular items. (Office file 73/M8/7425, 1973).
