A manual telephone exchange, manufactured by British Ericson, History Originally in use at Cohuna. When Cohuna was converted to automatic dialing this exchange was relocated to Harcourt, to become the third and last in a bank of three exchanges. At this time Harcourt exchange was expanded to 260 lines. It was connected to the district central exchange at Castlemaine. Operated by mains power with battery back-up. Harcourt exchange was operated by Betty McLean, Miss Mitchell, Josie Hogarth, Mr. & Mrs. Heighway, Bill & Valerie Milford, Irene Bolitho and others. Decommissioned approx. 1970. Incoming calls prompted the fall of a shutter. The operator made the connection by plugging the line into the number requested. While responding to calls the operator needed her hands free to jot down the billing particulars or to write out each telegram. Nearby stood pigeonholes with various items of stationary. Many telegrams were received each day, particularly advising fruit growers on interstate markets. Most telegrams were phoned through by the operator. This exchange was restored in 2004 - 2005 by Trevor Grant.. Many people relate to this exchange. It is a survivor of the pre-electronic era when ‘telephonist’ was a common occupation. A vital element in the communications between households and between district orchardists and their suppliers and clients.A manual telephone exchange, manufactured by British Ericson complete with operator hands-free headset/earphones and speaker mouthpiece.

The "Burroughs Calculator" was a non-printing key-driven machine introduced in 1912 in response to the success of the Felt & Tarrant "Comptometer". The first Burroughs key-driven machine was very similar to the Comptometer in its external appearance, but was quite different in its internal mechanism, with the register and carry mechanism based on a complex system of planetary gears. It was only about two-thirds of the weight of the Felt & Tarrant machine, and had none of the safety features. In particular, there was no protection against incomplete keystrokes in either direction. The register would simply advance in proportion to the depth of stroke, with no indication of error. However, the price was also about two-thirds of the Comptometer, which made it quite a popular (if dangerous) machine. (http://home.vicnet.net.au/~wolff/calculators/Burroughs/Burroughs.htm) The Burroughs Portable Adding Machine introduced in 1925 became the basic design for the adding machine for many years, until the ten key adder was introduced and started to replace it gradually. The key-driven type machine did not print, and while it was often used as an adding machine, it developed into a special purpose machine in later years. The machine was very fast . The efficient operation of these machines required an experienced operator who often received a high salary. The machine was produced over a very long period because of its unique capabilities and was often used to verify product delivery lists from delivery routes. Later models of the machine, called a duplex design, could hold a running total in a second set of dial wheels while the primary wheels continued to add and subtotal amounts that could be transferred at any time to the running total. A side note, Burroughs copied the Felt design for its first models and was sued for patent infringement by Felt and Tarrant who prevailed in the suit. As a result, Burroughs totally redesigned their machine and went on to compete with the Felt machine for decades. Info from (http://www.burroughsinfo.com/group_d.htm) Black metal low keyboard manual adding machine. The key-driven type machine did not print, and was exceedingly fast and experienced operators could easily outrun an operator on a full keyboard or 10-key adding machine. The adding machine has a brown leather carry case.calculator
