The core memory of this calculator was a #D metal box. The pin must have been attached to a card reader or keyboard to enter the programme. According to Sharp’s serial numbering scheme, which encodes the month and year of manufacture of their electronic calculators at least through the mid-1970’s, this calculator was manufactured in September 1969. The technology used in the Memorizer 30/Memorizer 60 was very typical of that of the late 1960s, with small-scale integrated circuits containing a few gates or flip-flops, and a magnetic core memory array for storing the program steps that the user keyed in using the calculator attached to the device. (with thanks to Rick Bensene, Curator of the Old Calculator Museum, Beavercreek, Oregon, USA) ISharp Memorizer 60 (Model CSA-12). The Model CSA-12, called the "Memorizer 60", was an accessory that could be connected to a Sharp Compet 22 or Compet 32 electronic calculator to allow these machines to be "learn mode" programmed. Programs were "learned" from the keyboard of the calculator, and stored within a core memory array in the Memorizer 60. Programs of up to 60 steps could be stored. The Memorizer 60 could them "play back" the stored steps at high speed, to allow relatively complex math operations to be performed.

The Axminster Carpet Loom has been set up as a focal point in the centre of the National Wool Museum. The loom was originally built by Brintons in England around 1910 and was initially operating in Geelong in 1960. Brintons designed and built most of their own looms and ancillary equipment. When superseded in 1975 the loom was donated to the Melbourne College of Textiles for weaving training. The College has now donated the loom to the National Wool Museum and Brintons engineering staff has restored it to full working condition. This loom is known as an Axminster gripper loom. The gripper system was invented by Brintons in 1890 and operates using a gripper shaped like a birds beak. This grips the yarn, the yarn is then cut and the gripper swings down to place the tuft into the woven backing. This particular loom also uses a jacquard system for weaving colours. In jacquard weaving, punched cards are used to instruct the loom as to which colour to use. The system was invented by Joseph Jacquard, a silk weaver from Lyon, and was introduced in 1804. It revolutionised pattern weaving as it had the capacity to create intricate patterns through the use of the cards. By 1833 there were approximately 100,000 power-looms used in Great Britain that had been influenced by Jacquards invention. Joseph Jacquard died in 1834. Charles Babbage was later to adapt Jacquards punch-card system to produce a calculator that was the forerunner of todays methods of computer programmingAxminster carpet loom featuring over 1000 Jacquard punch cards and over 100 bobbins of different colours of wool.loom carpet wool, geelong woolbrokers' association, geelong, auction
