Casio AL-1000 calculator, 1967

Object statement
Electronic programmable calculator, AL-1000, with cover and instruction manual, metal / plastic / electronic components / paper, made by Casio Computer Co Ltd, Tokyo, Japan, 1967
The A-1000 is one of the very first electronic programmable calculators. (The Casio Company claims it is the first). It is a desk-top calculator that uses transistor electronics, ferrite core memory and Nixie tubes for numeric display. While its applications were restricted to mathematical calculation it anticipates the arrival of personal computing.
Manufactured in Japan by Casio, 1967.
The calculator was originally owned by Helmut Bonzol (the donor's father) who used it for engineering calculations in his work with the company Pre built Steel Constructions which made pre-fabricated steel constructions. The company was started, c.1955, by Bonzol with two friends. One was the person who sponsored the Bonzol family to Australia and the other was a cousin (donor's uncle ?). Bonzol had trained as a boilermaker but due to the war did not get his full engineering qualifications. He worked in construction in the UK before the family emigrated to Australia in 1954/5(?).

The donor has described Bonzol as being always interested in the latest gadget of which this calculator was a good example at the time of purchase - soon after its appearance on the market in 1967.

His company did work for Boral making all their tanks [see http://www.boral.com.au/history/] - including what the donor described as the "sputnik" styled spherical (LPG?) ones. They also designed and manufactured suspended and hanging awnings for Mirvac. Other work included warehouse fabrications.
