In 1885 Julius Pitrat of Gallipolis, Ohio, patented the first computing scale. Six years later, Edward Canby and Orange Ozias of Dayton, Ohio, purchased Pitrat's patents and incorporated The Computing Scale Company as the world's first computing scale vendor. And four years after that, The Computing Scale Company introduced the first automatic computing scale In 1911. the Computing Scale Company merged with the International Time Recording Company and Tabulating Machine Company to form the Computing-Tabulating-Recording Company, a business that was renamed IBM in 1924. An early example of a hanging clock face scale patented in October 1897 and made by a company that pioneered the first computing scales used in retail businesses. This company went on to become incorporated with IBM that late became an international computer manufacturer.Scale, patented Oct 12, 1897. Measures in pounds and ounces, up to 10lb.

This 'Dayton Scale' was used in a grocery shop in Moorabbin Shire in 20thC to measure grain, sugar, fruit, vegetables, lollies, etc as required by the shopkeeper for the purchase by customers. The Dayton Scale Company, originally known as the Computing Scale Company, built and marketed the first computing scale in 1891. It was part of the Computing-Tabulating-Recording Company formed in 1911, and became an IBM division in 1933. The Dayton Scale Division was eventually sold to the Hobart Manufacturing Company when IBM decided to stop marketing scales to retail stores. The Computing Scale Company of Dayton was operated from 1891-1914 by two businessmen from Dayton, Ohio who purchased patents on the recently invented computing scale. It was merged with other companies to become the forerunner company for IBM. On July 20 1897 Mr CC Hobart & Herbert L. Johnson formed the Hobart Electrical Manufacturing Company in Troy, Ohio USA. 1915 Hobart continues its growth into the World market, opening a sales office in Australia.

The Ferranti Sirius is an electronic second-generation transistor computer and is one of three remaining examples of this machine left in the world. It was an important addition to the computing facilities at Monash University in the early 1960s and provided access for computer programming and research for many early computer professionals, academics and teachers. The Ferranti Sirius computer was built in a period of rapid growth in computing technology. The first stored program computers appeared in the late 1940s and used individual designs with valve technology. By the mid-1950s valve technology was replaced by transistors and the first mass produced commercial computers became available. The Ferranti Sirius was announced in 1959 and offered a “small” academic computer. It was designed and built by the English company Ferranti Ltd and sold through a local office of the company in Melbourne. The Sirius was manufactured at the Ferranti Ltd.’s West Gorton, England factory from 1959 to 1963 and, in all, the company produced probably 22 installations although only 16 were actually recorded as sold; this included one at Ferranti’s Bureau in London and one at Ferranti’s Melbourne Bureau. Only 7 were exported and 4 of these 7 were located in Melbourne, Australia. All four were associated with computing at Monash University – the Sirius in the MMoCH collection was purchased by Monash University in 1962, a smaller Ferranti Sirius was used on the Caulfield campus (prior to amalgamation with Monash University) from 1963, the Ferranti company had its own Ferranti Sirius initially temporarily installed at Clayton campus in 1962 and then placed in their office in Queens Road, Melbourne. A fourth computer was purchased by ICIANZ (now Orica) in 1962 and was transferred to Clayton campus in 1967. Only two of these Melbourne examples have survived; one in the MMoCH collection and one at Museums Victoria. There is an example of the Ferranti Sirius in the Science Museum Group collection in the UK as well. The Ferranti Sirius in the MMoCH collection was the first computer purchased by Monash University and it was shipped to Australia to be installed by November 1962. The University had a similar model computer on loan from Ferranti Ltd during the first part of the year and it was returned to the office of the company in Queens Road, Melbourne once the University’s own machine was installed. The computer was placed on site at Clayton campus, Monash University. The computer operated from 1962 until 1972 when it was officially decommissioned. The Ferranti Sirius was sold to Mr Paul Stewart in late 1974 and removed from Monash University. Mr Stewart later donated the computer back to the University in 1988 and it was transferred to the collection of the Monash Museum of Computing History after 2001. The Ferranti Sirius is an electronic second-generation transistor computer and is one of three remaining examples of this machine left in the world. It was an important addition to the computing facilities at Monash University in the early 1960s and provided access for computer programming and research for many early computer professionals, academics and teachers. The Ferranti Sirius is of scientific (technological) significance as one of the early transistor digital computers that transitioned computing from first-generation valve computers to second generation commercial installations. This example of the Sirius is of historical significance in its role as a part of the Computer Centre, Clayton campus, Monash University which provided computing facilities in Melbourne in the early 1960s when there were few installations available for academic, administrative and commercial users. Staff and students were able to undertake investigative research and learn programming techniques. The Computer Centre encouraged the use of the computer across all disciplines and this provided the base to establish computer science as a subject offering and, later, a new department in the University. This growth in computer education eventually culminated in the establishment of the Faculty of Information Technology, Monash University. The Ferranti Sirius in the collection at Monash Museum of Computing History has a main unit with a CPU and memory combined with input/output equipment and one extra cabinet of memory. The Central Processing Unit is a floor-standing unit which contains the computer circuits, power supplies and has a decimal digit display panel and a normal clock. A moveable control panel is placed in front of the Unit (Currently set on a recreated desk/filing cabinet support in the display). The Sirius base unit uses acoustic delay line memory with 1000 word store. An additional 3000 word memory cabinet is set adjacent to the CPU and can be connected to increase the memory. The computer is supported by a range of input/output devices. There is a Ferranti Paper tape reader, located on desk in front of CPU. Red label on front “Ferranti tape reader. Type TR 5. Serial No. 477”. Adjacent to the CPU is a set of Simplified tape editing equipment in three pieces which includes a (1) Table unit with switches on front face. Metal tag on reverse reads “Creed & Co. Model No. S4060. Serial No. 1457. Original Customers Marking GRP7 V706”. The table has a numbered internal tag “Table Serial No. 198579. (2)Creed teletype set on table unit. Metal tag on reverse “Creed & Co. Model No. 75RPR K4M4. Serial No. 5897 Made in England”. (3)Creed paper tape reader set on table unit. This set of equipment could read paper tape and print it, or copy paper tape while allowing it to be edited, or allow a programmer or data preparation person to type and punch a new program or data. It has no electrical connection to the computer. Paper tapes were usually torn off and carried across to the computer. There is also another table unit with switches on front face and changeable setting switch on front right side which holds a Ferranti Westrex paper tape punch set. Label on reverse “Teletype Code BRPE11” This was the Computer’s only output device. BRPE-11 is a teletype model number.

The Kew Historical Society's postcard collection includes views of Kew, Melbourne and Greater Melbourne as well as those including overseas scenes sent or received from Europe or the Middle East. They date from the 1890s to the 2000s. These postcards may or may not include the name of the publisher or printer. A number of the cards were published as parts of popular series. A way of dating early postcards is to identify whether the reverse was divided by a central line which became the norm after 1902 in the United Kingdom. However, other postcards produced after this date do not always conform to this print layout.Colour postcard of the interior of St Paul's Cathedral, Melbourne by Max Ahearne, Renwick Pride, Gravure Print.St Paul's Cathedral, Melbourne, Australia - Sanctuary / Foundation stone, 1880; Consecrated 1891; Spires computed 1931.

First available in ScubaPro’s catalogue in 1966, the ScubaPro Automatic Decompression Meter was a break through in diving technology and a forerunner to the modern dive computer. The meter attempted to calculate nitrogen absorption based on dive time and depth. This was done mechanically instead of electronically, and without the benefit of any actual computing. The Automatic Decompression Meter was introduced just a year after ScubaPro’s most successful product – the ScubaPro Jet Fins – which still remain popular today.

This is a set of 30 photographs of Royal Australian Survey Corps (RA Svy) personnel from Central Comd Fd Svy Unit (Adelaide) on Aerodist survey operation - Project C4 in Eastern Arnhem Land, Northern Territory in 1967. Photos of personnel were taken either at the operations base at Numbulwar or the main base at Gove (Nhulunbuy). RA Svy conducted nineteen Aerodist operations for 12 years from 1964 to 1975. Aerodist MRC2 was a tellurometer-based system adapted for aircraft to accurately measure distances between non-intervisible ground survey stations, using the aircraft as an intermediate station. Lower order geodetic results could be achieved by survey network trilateration. The measured distances between stations formed survey networks from which each station’s latitude and longitude was computed. Aerodist MRC2 was RA Svy’s major horizontal control survey tool for mainly medium scale topographic mapping (scale 1:100,000 Class A being spatially accurate to within 50 metres) in PNG, northern NT, north-west WA, Kalimantan Barat (West) Indonesia, Sumatra Indonesia, Gulf of Carpentaria and Cape York, QLD. In 1967, the Aerodist MRC2 Master equipment was installed in the aircraft featured in this set of photos, Executive Air Services’ (Essendon VIC) Grand Aero Commander VH-EXX. It was the same aircraft type and company contracted to Division of National Mapping for Aerodist MRC2 surveys. From July to October 1967 the aircraft was attached to Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) on Project C4 eastern-Arnhem Land NT, where 317 Aerodist lines measuring 17,300 line miles were successfully completed. This was the most productive Aerodist project thus far. The most common helicopter used by RA Svy up to 1972 was the civilian Bell 47G-2 and the Sioux Light Observation Helicopters (LOH), the Australian Army’s equivalent featured in this photo set. These light observation helicopters had a limiting load carrying capacity of up to about 500 pounds. By comparison, one Aerodist team including two people weighed up to 1,500 pounds.

This collection of 17 photographs of Air Survey Squadron aerotriangulation equipment and personnel was taken at the Army Survey Regiment, Fortuna, Bendigo, circa 1989. The PDP 11/70 minicomputer was the operating system introduced in 1977 as the mainframe system for the control of the APC4, aerial triangulation block adjustments, SORA OP Analytical Orthophoto control, APR Analytical Terrain Profile Recorder computation, graphics, and general computing. The OMI/Nistri AP/C-3 analytical plotter shown in photo .1P to .6P and .9P was introduced in 1972–1973. The Zeiss (Jena) Stecometer analytic stereocomparator for air photography shown in photo .16P was introduced at Air Survey Squadron in 1963. Aerotriangulation production was expedited using computers for analytical photogrammetric processes. The technician accurately measured between pass, tie, and survey control points on aerial photographs. Wild PUG4 point transfer devices as shown in photo .17P, were introduced in c1968 superseding the PUG2 devices. PUG4 devices were used by technicians to stereoscopically view the photography containing the survey control points and the mapping aerial photography. The Control points were transferred from the control photography to the mapping diapositives of aerial photography by drilling their locations into the photographic emulsion. See item 6195.19P for more photos of aerotriangulation equipment and their operation in map production.This is a set of 17 photographs of Air Survey Squadron aerotriangulation equipment and personnel taken at the Army Survey Regiment at Fortuna, Bendigo, circa 1989.

These flow diagrams and in particular the Introduction to Automap 2 booklet is designed to provide a general description of the second phase of the AUTOMAP system (Automap 2) installed at the Army Survey Regiment, Bendigo. It contains information that managers and supervisors need to know and serves as a preliminary introduction for anyone interested in learning about AUTOMAP 2. In addition, a number of annexes are included to provide more detailed descriptions of significant features and components of the system. System Objectives. In order that RASVY can carry out its mapping programme effectively, an efficient production system is required that can acquire and edit digital data from a topographic data base and thence automatically produce high quality maps using that digital data. The existing system, AUTOMAP 1, provides a small part of such a system. AUTOMAP 2 expands the capabilities of AUTOMAP 1 in data capture, computing power and data handling for cartographic purposes. AUTOMAP 2 includes state-of-the-art technology, introduces interactive graphics as a production tool and shifts procedures from a current mix of analogue and digital technologies to an almost totally digital system. AUTOMAP 2 increases map production by at least 20 percent at the Army Survey Regiment. Project References. A wide range of user manuals and associated documentation is available for both the hardware and software components of the AUTOMAP system.
