The Micro-Professor I Plus (MPF-IP) was a low cost, versatile microcomputer system featuring sophisticated software and hardware capabilities. (MPF-IP) boasted a display panel with the ability to display 20 characters using 16-segment fonts. All 64 standard ASCII characters could be displayed. The operation of the MPF-IP was controlled by an 8k monitor program which resides in the Read Only Memory (ROM). The monitor, aided by 4k Random Access Memory (RAM), enabled the user to enter a comprehensive set of single keystroke commands, making it easier for the user to use the CPU, memory and I/0 devices. This allowed the user to concentrate of microprocessor software development and application design. The system allowed printing at 48 lines per minute, and the ability to permanently record the commands, data, programs, status and other messaged. Each character printed by the printer is in a 5 by 7 dot matrix. Although the prime purpose of the programming was for machine language object code formed as hexadecimal numbers, the Micro-Professor has an embedded Tiny Basic interpreter for which formation of some of the alpha characters using a standard 7 segment display was ingenious. The program memory consisted of non volatile 2 kilobytes electrically programmable ROM whilst the Random Access Memory came with 2 kilobytes of static RAM but could be upgraded to 4 kilobytes by insertion of another chip. The entire memory space of 64 kilobytes was accessible by way of the terminals on the left hand side of the board. Engineering and Science students from the Ballarat School of Mines and the Ballarat College of Advanced Education used a class set (as they were relatively inexpensive at approx. $100 each) during the mid to late 1980s. Student were encouraged to borrow the Micro-Professors in order to assist in learning how to use them. Only one was ever not returned on time. When pressed to return the device the student confessed that his dog had chewed the plastic case. This is still in our collection complete with bite marks! The Micro-Professor used a Zilog Z80 microprocessor. This was the most powerful of the 8 bit microprocessors at the time. Zilog was derived from the Intel 8080 microprocessor. The Z80 had 158 instructions of which the Intel 78 instructions were a subset. The Intel processor continued on through development in the IBM computers as 8086, 80286, 80386, 80486 and later the pentiums. Zilog lost most of its market share when it developed the 16 bit Z8000 microprocessor. Although the microprocessor was excellent, the lack of peripherals caused users to abandon Zilog products.

Information from Norman F. Dalton: Ballarat had a reticulated DC supply in the early part of last century and in 1905 had sufficient generating capacity to enable the trams to be changed from horse drawn to DC electricity. The use of electricity increased with the main power station located on Wendouree Parade, near Webster Street, under the ownership of The Electric Supply Company of Victoria. AC generating plant was installed in 1925 and conversion to AC proceeded. In 1934 the company was taken over by the State Electricity Commission Victoria (SECV) and more AC generation was installed and the changeover of customers was accelerated. This is around the time that the Synchronome Frequency Checking Mast Clock was installed at the Wendouree Parade Power Station. The SECV Annual Report of 1921 states: ::Section 11 of the act directed the COmmission to enquire into the question of securing the adoption of such standards of plant and equipment of a system, frequency and pressure for the generation and distribution of electricity as will admit of the efficient interconnection of undertakings throughout the State. In 1934 when the SECV took over the Ballarat operations the question of linking with the State grid had been a planned operation for some years but due to financial considerations had hindered it and in fact would continue to do so for a further 10 years. So while the need for close frequency control for interconnection was hardly an issue, the need to keep electric clocks correct was important, particularly as this item was a frequent sales point to cover the inconvenience and sometimes expense of converting from DC to AC. The clock is a very accurate pendulum clock with provision for varying effective length during operation for precise time regulation. There are two normal time dials and one is controlled by the pendulum and the other is operated by the system frequency. When the clock was in use it was installed by the MEter and Tests Laboratory and the time was checked daily by radio time signals. The two dials were repeated in the operators control panel in the Power Station. A maximum deviation between the two dials was set in the operating instructions (eg 5 seconds) and the operator would correct this when necessary by remote manual alteration of the turbine governor set point. The clock was used to drive and regulate a system of "slave" clocks which were used to display the time in various locations around the power station. A slave clock is a simple clock which is driven by a small electric motor, its accuracy is regulated by the master clock every 30 seconds to ensure that it and all the other slave clocks in the station are on exactly the right time; slave clocks were placed in various locations, from common rooms to workshops. A master clock could potentially run thousands of slave clocks at one plant. The clock also contains a rectifier. A rectifier is a device that is used to convert AC power to more stable DC current.Two clocks in a timber case. Both are electric, one is powered by the main pendulum mechanism, the other is a self contained electric clock. The main mechanism is of the gravity arm and roller type, which sends an impulse to the slave clocks every 30 seconds. The This Synchronome Frequency Checking Master Clock was used at the Ballarat Power Station. Below the main section of the case is a smaller cabinet containing a rectifier to provide consistent DC power for the clock. The rectifier was made by the Victorian company Hilco, which was located in Burwood. There is a high chance this is not the original rectifier from this clock as there appears to be brackets to hold a larger device in the space the rectifier occupies.Front below main clock face on front of case: "Patented Sychronome Brisbane" Lower left-hand clock face: "Frequency time" Lower right-hand clock face: "Standard Seconds" Synchronous electric clock mechanism on door (Frequency time clock): >200/250 V. 50~ >"Synchronomains" Made in England >Direction indicator for clock starting switch >"To start move lever in direction of arrow and release" >"Patent applied for" Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for main clock face: >"English Made" >"Patented" >Serial number "8751" >0 above right-hand pillar on front-plate Inside case, back panel, top enamel plate: >Seconds Battery + Pos. > Battery Common or - Neg. >1/2 min dials Inside case, back panel, bottom enamel plate: external seconds dial Inside case, right hand side, electrical knobs: two switches, both "A.C. mains" Pendulum rod, below suspension spring: Serial number (?) 0000005 Rectifier in bottom cabinet: >"Hilco Rectifier" >"A.C.

Francis Hardy Faulding 1816 – 1868 arrived in Sydney 1842. He was a Surgeon on the emigrant ship Nabob. 1845 Francis Hardy Faulding opened his first pharmacy at 5 Rundle Street in Adelaide and the business prospered. In 1867 he formed F.H Faulding & Co with Luther Scammel. as wholesale druggists and manufacturing chemists. Two of the Faulding company's major innovations were the development of a process for distillation of eucalyptus oil, and the development of the test for determining the eucalyptol content of the oil. Faulding's success was founded on eucalyptus oil, which formed the basis of an antiseptic marketed as "Solyptol" In 1868 Francis Hardy Faulding died, aged 52 at his suburban Glen Osmond home in Adelaide. Scammel’s two sons took over the business in 1888 and in 1890 the Company expanded to West Australia, then Sydney, Brisbane and finally, in 1924, Faulding began operations in Exhibition Street, Melbourne, eventually adding wholesale activities. 1986 With a presence in every city, from Darwin to Tasmania.

Australia's first telephone exchange was opened in Melbourne in August 1880. It was operated by the Melbourne Telephone Exchange Company. Owned by W. H. Masters and T. T. Draper, the Manager of the Company was H. Byron Moore. This was only two years after the world's first exchange in the United States, and just four years after Bell first spoke on a telephone. The exchange was located in the old Stock Exchange building at 367 Collins Street, a site now occupied by the Commonwealth Bank. In 1884, the operations of the Company, by then known as the Victorian Telephone Exchange Company, had grown considerably and were transferred to Wills Street, Melbourne. Private ownership of this company continued until 1887 when it was bought out by the Victorian Colonial Government. Other colonial governments followed this example. By 1910, the growth in telephone services made additional accommodation necessary. This could not be provided in the existing building in Wills Street and arrangements were made for a new exchange in Lonsdale Street. Alexander Graham Bell visited Australia in 1910 to advise the Federal Government's Postal Commission. Telephone exchanges were established in Adelaide with (48 subscribers), Hobart (10 subscribers) and Launceston (35 subscribers). The first exchange in Western Australia was established in 1887 and located in a small three-room cottage in Wellington Street, Perth with 17 subscribers. The year 1888 marked the opening of the Fremantle exchange in a small room at the rear of the Town Hall. There were nine subscribers. Australia's first automatic exchange was installed in the GPO in Sydney, in 1911, for internal use. But the first automatic exchange for public use was opened at Geelong in Victoria in the next year July 1912 with 800 subscribers. Melbourne's first automatic exchange was opened in the suburb of Brighton in 1914; the first public automatic exchange in NSW began operating at Newtown, Sydney in 1915; and Queensland's first was installed at South Brisbane in 1925. 1929 saw the opening of Tasmania's first automatic exchange in Hobart. an automatic telephone service. In June 1977, the manual telephone exchange at Swansea was replaced with an automatic service and made Tasmania the first State in Australia to have a fully automatic network. The half-century following Federation saw the growth of the automatic operation; a great extension of trunk line services; The automatic telephone contributed greatly to the early popularity of telephones in Australia. It was a quicker and more convenient way of communicating with another person on the same exchange — instead of having to go through tedious processes with the operator. From its introduction, the number of automatic telephones in operation grew to a remarkable extent. In 1886, the first trunk link of 16 km was connected to the exchanges of Adelaide and Port Adelaide in South Australia. Then, in 1907, the first inter-capital telephone trunk line was opened between Sydney and Melbourne. It was followed by a line between Melbourne and Adelaide in 1914. Sydney and Brisbane were linked in 1923, and Perth and Adelaide in 1930. In 1930, the first overseas calls from Australia came possible with the introduction of a radiotelephone service to England, and through there to Europe and America. A similar service opened to New Zealand in the same year. Initially, trunk channels linked different manual trunk exchanges. It was necessary for a succession of trunk operators to connect the appropriate channels, one after the other until the connection was made. As trunk traffic grew. the system became increasingly unsuitable. More trunk operators had to be employed and so labour costs increased. It was a tedious and slow way of making a long-distance call, and it was sometimes hard to hear, particularly when several exchanges were linked With technical advances, trunk switching moved from manual operation through a partly automatic phase. Automatic transit switching equipment was used and only a single operator was required to connect a trunk call to a wanted automatic subscriber. Until well beyond the middle of this century, the majority of trunk traffic went through this single telephonist control. In 1953, the number of telephones in use in Australia passed the one million mark. By then, the need for improvement in the automatic exchanges was becoming well recognised. The need was for a telephone switching system which would do a better job more economically than the conventional step-by-step ex-change. This led to the adoption of the Crossbar system as the standard in automatic telephone exchanges in 1960. The introduction of Crossbar switching was a big step forward in the automation of trunk calls. It substituted automatic switching and charging equipment for the originating trunk operator, and improved the quality of the system radically. Before the introduction of the Crossbar system there were often very long delays in obtaining a booked trunk call, and the quality of sound was often very poor. With Crossbar, Subscriber Trunk Dialing (STD) became a reality. A trunk call by STD was as easy to make and almost as fast to connect as a local call.The item was made around the 1940s and used up until the 1970s in manual cord telephone exchanges as a way to time and charge users for trunk calls made over the telecom system of the time.

The Postmaster-General's Department (P.M.G.) of Australia was created in 1901 with Federation taking control over all six Colonies (States) Postal and Telegraphic services within Australia to form the national Postal and Telegraphic services within Australia. The Department was administered by the Postmaster-General. This manual was produced as a syllabus of training for Army Personnel units in P.M.G's Department schools.In war times the postal organisation was a vital link between the services, the community and overseas centres. The Postmaster-General's Department co-operated with service departments in the installation and operation of radio, telephone and telegraph systems. Its laboratories also designed, developed and manufactured vital defence equipment. This item reflects that contribution and history.A 31 pp buff colored book with orange cloth binding.

This is a set of 26 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 .4P to .26P) and in Western Arnhem Land, Northern Territory in 1968 (photos .1P to .3P). 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. In 1968, after completion of the Kimberley Aerodist Operation project, the Aerodist system in VH-EXX was immediately deployed to western-Arnhem Land NT for Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) to complete the mapping control across northern NT from mid-July to October. The Aerodist MRC2 Remote antenna seen in Photos .24P to .26P is mounted on a 20 foot pole tower. The antenna direction was controlled by wires/ropes to the two arms under the dish at right angles. The antenna elevation could be changed to the vertical for aircraft height checks as seen in photo .25P. Source: Royal Australian Survey Corps – Aerodist Years 1964-1975 by Peter Jensen.

This is a set of four photographs of WO2 Graham Ragless from the Royal Australian Survey Corps demonstrating the operation of Global Positioning System equipment in c1988. The photos were probably taken at the School of Military Survey (SMS), Bonegilla, VIC. Texas Instruments TI4100 portable Global Positioning System (GPS) geodetic receivers were introduced from 1986–1988. The GPS receivers and Ferranti FILS3 helicopter and vehicle mounted Inertial Positioning System (IPS) replaced the TRANSIT satellite receivers. The equipment was deployed to establish the baseline for a GPS controlled air camera and photogrammetric system to significantly reduce the requirement for ground survey to accurately control air photography for topographic mapping. Personnel from the four field survey squadrons at this time were trained at the SMS to operate the TI4100 receivers. Field survey operations using GPS and IPS equipment followed in the late 1980s. This technology is described in more detail in the RA Svy booklet titled An Introduction to Topographic Mapping. See record ID - 6010. WO2 Graham Ragless progressed to the rank of WO1 and was appointed as RSM of the Army Survey Regiment from 1990 to 1992. Refer to item 6186.2P for more photographs of WO2 Graham Ragless demonstrating the TI4100.This is a set of four photographs of a technician from the Royal Australian Survey Corps demonstrating the operation of Global Positioning System equipment in c1988.

Protective relays are one of the critical components of the elctrical power grid that serve to detect defective equipment or other dangerous or intolerable conditions and can either initiate or permit switching or simply provide an alarm to provide an alarm to provide a safer, more reliable delivery system. Used in power stations. The function of relay is to quickly remove from service any equipment that might suffer damage or otherwise affect the operation of the system. Relays protect the electrical system in 2 ways: Prevent failure or damage to electrical systems. Mitigate the effects of failure when it occurs. Switches that control other switches. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal.Used by the State Electricity Commission of Victoria for the Kiewa Hydro Electric Scheme in the power stations. Manually operated by remote control for an external circuit breaker. The relays were from a Kiewa Hydro Power Station control panel.Collection of black metal rectangular boxes (heavy) containing electrical wires forming a circuit. The longer, narrower rectangles have a bakelite knob at one end. Some of the boxes have one side of clear perspex and another has all sides of clear perspex. One is labelled "group relay". Another has windows with labels eg. 'turbine overspeed' 'emergency trip' and one has 3 steel knobs. - with 'stop', 'start'. One box is larger than the rest and has clear perspex side showing 'overcurrent relay' and workings.One has a plaque attached. Manufacture: "The English Co. Ltd.

This Favag Timer apparatus was a part of the first electronic control system -(1960's), in Victoria), which worked using telephone stepping selectors to convey a change in voltage providing a regulated pulse from the control centre(Mount Beauty) to the remote Power Stations opening and closing (stop/start) of various devices at the Power Station and a return signal confirmed the action taken. Testing of this unit was carried out using a "dummy" device at the remote Power Station so as not to disrupt the power plant's operation. This timer was one of many electrical apparatus connected to the large SEC Victoria Hydro Scheme's electrical power producing generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro Schemes was achieved from the early 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce,inclusion of skilled and unskilled, migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.This Favag Timer was one of the crucial pieces of equipment that made it possible for the Mount Beauty Terminal Station to control the operations of these Power Stations; McKay, Clover, West Kiewa Power Stations and the Dederang Terminal Station.This aluminium and anodised "FAVAG" (pulse) timer is fastened to a base structure which comes with its own metal cover that is fastened by two metal hooks. From the top of these hooks runs a thick leather "carry" strap.The instrument, itself, a small "micro motor" at one end tape feeding spool on the other. Aluminium metal structures offer a preventative barrier against any electronic spikes from static electricity sources. There are two toggle switches to the bottom right hand side and twelve coloured "pin" connection points.There is a sliding access sleeve which exposes a circuit board.with various leads fastened on each side. In front of one of this slide are two "screw in" fuses, spare fuses are in a small envelope taped above. Circuit diagrams are etched white on black background on the top face of the main structure. At the base of the back section is a two pronged input terminal. There is a fine black rubber layer (cushioning) for the mian top cover.On the cover fastened with two rivets "FAVAG" underneath in small print "Fabrique d'appareils electriques S.A." underneathe "NEUCHATEL-SUISSE". on one end is a "STATE ELECTRICITY COMMISSION OF VICTORIA" metal label screwed on.The back label has manufacturers' type and model number.sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth

This is a set of two photographs of WO2 Graham Ragless from the Royal Australian Survey Corps demonstrating the operation of Global Positioning System equipment in c1988. The photos were probably taken at the School of Military Survey (SMS), Bonegilla, VIC. Texas Instruments TI4100 portable Global Positioning System (GPS) geodetic receivers were introduced from 1986–1988. The GPS receivers and Ferranti FILS3 helicopter and vehicle mounted Inertial Positioning System (IPS) replaced the TRANSIT satellite receivers. The equipment was deployed to establish the baseline for a GPS controlled air camera and photogrammetric system to significantly reduce the requirement for ground survey to accurately control air photography for topographic mapping. Personnel from the four field survey squadrons at this time were trained at the SMS to operate the TI4100 receivers. Field survey operations using GPS and IPS equipment followed in the late 1980s. This technology is described in more detail in the RA Svy booklet titled An Introduction to Topographic Mapping. See record ID - 6010. WO2 Graham Ragless progressed to the rank of WO1 and was appointed as RSM of the Army Survey Regiment from 1990 to 1992. Refer to item 6226.4P for more photographs of WO2 Graham Ragless demonstrating the TI4100.This is a set of two photographs of a technician from the Royal Australian Survey Corps demonstrating the operation of Global Positioning System equipment in c1988.

This is a set of five photographs of CAPT James ‘Jim’ Leslie Stedman in the field demonstrating the setup of prisms used as electric distance measurement (EDM) receiver reflectors for tellurometer equipment and the sighting of a large surveyor’s light. This equipment was deployed in establishing mapping and geodetic control operations. The photos were most likely taken in the late 1950s or early 1960s. The tellurometers of this era were man-portable systems that improved geodetic survey efficiencies for rapid network extension and densification replacing triangulation with EDM and theodolite traverse sometimes using Bilby Towers to extend line lengths. Jim Stedman later reached the rank of Colonel, was Director of Military Survey from 1975 to 1978 and was appointed as Colonel Commandant (honorary appointment, Retd) of the Royal Australian Survey Corps from 1978 to 1983. Jim Stedman is demonstrating EDM equipment. See item 6180.16P, photos .14) to .16) for more information and photos of Jim Stedman’s EDM demonstration.

Radio Telephone was minuted during the war. It was approved in 1944 for State Electricity Commission of Victoria use only. It was completed by the end of 1946. Used by the State Electricity Commission of Victoria at Bogong during the construction of the Kiewa Hydro Electric Scheme to connect with head office in Melbourne. It allows one conversation at a time using traffic controls in an unusual system of radio telephone providing communication. At the time it was unique in Australia and installed by the S.E.C.V. technicians. It provided an unattended shortwave radio link between two ordinary telephone switchboards, connecting any of the S.E.C.V.'s internal lines with the telephone system at Bogong and the construction camps beyond. From Bogong, radio phones connect to the outpost stations on the High Plains far above the snow-line. In operation, the service is similar to a normal telephone system but dispenses with the physical connection of wires and poles between the main terminals. Historical: This type of headphone was recommended for amateurs. It may have been used by operators on the Switchboard at Bogong or one of the construction camps on the Kiewa Hydro Electric Scheme.

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.
