Ferranti Sirius mainframe computer, 1961
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. -

Personal Effects. 'Philips" electric Shaver, c1977
Established in 1891 in Eindhoven, the Netherlands, Philips & Co. was founded to meet the growing demand for light bulbs following the commercialization of electricity. Science and technology underwent tremendous development in the 1940s and 1950s, with Philips Research inventing the rotary heads that led to the development of the Philishave electric shaver, and laying down the basis for later ground-breaking work in transistors and integrated circuits.Philishave was the brand name for the electric shavers manufactured by the Philips Domestic Appliances and Personal Care unit of Philips They used the Philishave brand name for their shavers from 1939 to 2006. The Philishave shaver was invented by Philips engineer Alexandre Horowitz, who used rotating cutters instead of the reciprocating cutters that had been used in previous electric shavers. The shaver was introduced in 1939, though initial production was limited due to the outbreak of World War II. A more ergonomic egg-shaped single-head model was introduced in 1948 and was designed by US industrial designer Raymond Loewy. Global sales increased markedly after a double-head model was introduced in 1951. As a spin off from the light bulb and research is the dynamo-powered bicycle lamp. Its rotating power system inspires the Philishave triple head electric razor. A triple-head model was test marketed in Australia and New Zealand in 1956, but would not be introduced globally until 1966. The brand name Philishave was phased out in 2006 so shavers now bear only the Philips name. Mr Alfred William ( Bill ) Roper, 1913 - 1996 grew up in Ripponlea, ( East St Kilda ) Victoria.

Sonotone 700 Hearing Aid, Sonotone, 1946
Although Lee DeForest invented the triode vacuum in 1906, it was not employed in hearing aids until 1921. The first hearing aid using a vacuum tube was purported to have been made by Earl C. Hanson. He called his hearing aid the Vactuphone. It used one small peanut tube (below right) to amplify the output of a carbon hearing aid. The Globe Hearing Aid Company and Western Electric collaborated to manufacture the Vactuphone. By the early 1940s, Raytheon had developed miniature vacuum tubes. It was these miniature vacuum tubes that made body-worn hearing aids a reality. Unfortunately, the power requirements of these aids made it necessary to use two relatively large batteries—an "A" battery to power the filaments of the vacuum tubes and a "B" battery to supply the high-voltage for the plate current. The batteries were worn external to the hearing aid itself and the name "Two-piece" hearing aid was used to describe them. Until about 1945 "Two-piece" hearing aids were the norm. However, improved vacuum tube design reduced current requirements. As a result, battery manufacturers were able to reduce the size of the batteries used in hearing aids. At the same time, electronic components were also being miniaturized. This allowed the hearing aid manufacturers to design hearing aids with internal batteries. After 1945, these "One-piece" hearing aids quickly replaced the more cumbersome "Two-piece" hearing aids. With continuing improvements in both batteries and components, hearing aids continued to reduce in size until 1953 when the vacuum tube was suddenly supplanted by the transistor.Fawn plastic hearing aid with metal clip on back and wires leading from the bottom.

radio, C1950's
Old radios recall a time when society was very different. The 1950s were the heyday of radios in Australia. Families often had more than one in the home. When transistor radios arrived instead of listening on the valve mantel, people were able to grab a tiny radio, taking music and news anywhere they wanted. This item reflects the time before portable radio communication. A 240V valve radio in a wooden cabinet. It is a mantel radio with four knobs at the front - two on each side - for volume, tuning, tone/on/off and band. There is a lead with a plug attached and earth at the back. Under each corner is a small wooden foot. "S.T.C. Made in Aust."radio communication entertainment -

AWA Transistor Carphone
After the 1939 bushfires, the Forests Commission Victoria invested heavily in a radically new communications network. After suffering some inevitable delays due to the war, radio VL3AA switched into full operation in October 1945 proudly beaming out 200 watts across the State. But by today’s standards, the technology was primitive and the reception poor unless the user was on a high point somewhere. The radio signal was "line-of-sight" and bounced between fire towers and relay transmitters across the mountains back to the District offices. The advent of solid-state electronics in the 1960s replaced the more delicate valve sets which enabled greater use of vehicle mounted radios. The Commission continued to research, develop and build new radios at its many workshops around Victoria. The network was supported by a large team of skilled radio technicians. The more secure and versatile State Mobile Radio (SMR) digital trunk system came into operation in about 1995. Upgraded Tait Radios were purchased in 2014 after recommendations of the 2009 Bushfires Royal Commission. But it was the convergence of separate technologies such as 5G mobile phones, high-capacity and light-weight lithium batteries, Wi-Fi, the ever-expanding internet, cloud data storage, digital cameras, GPS, personal organisers and hundreds of supporting Apps into powerful smartphones and tablets which revolutionised bushfire communications from the mid-2000s.
