With a special thanks to Glen, who gave this to me as a gift. This was Llew's calculator from the 1970s who is Glen's father. This is one of my most treasured things. Glen's father was my boss when I was an Applied Physics student working at the AAT in 1985/86 and later in 1989 to 1996 when I worked as the AAT's User Support Coordinator.
Llew Cedric Denning, BEM, 01 Oct 1933 – 29 Nov 2014
"Llew Denning started his career as an apprentice in the RAAF at age 16, served in Japan after the Korean War and then did pioneering work on flight simulators, which led to the award of a British Empire Medal. He continued in this field with TAA (later part of Qantas) until he came to the AAT as head of the electronics group. He eventually took on responsibility for all operational activities for both the AAT and the UK Schmidt. After Peter Gillingham moved to the Keck Telescope in 1992, Llew succeeded him as Officer-in-Charge (later Operations Manager) until he retired in 1998. Llew could handle almost any technical problem that arose, and proved to be an ideal team manager and natural leader. He was always calm and quietly confident in a crisis. He epitomised the ethos that the AAO's top priority was to ensure that the equipment worked as well as possible, with minimal loss of time for visiting observers.He was all too often at the telescope out of normal work hours, a lifestyle facilitated by the fact that he lived on the side of Siding Spring Mountain. His herd of hairy Scottish highland cattle became a familiar if incongruous sight, sharing their fields with kangaroos and emus. Llew was a man with many other interests and abilities. Some of us will recall his performances in comedy sketches at the AAO's "Golden Dome" social nights, others may have been moved by the dramatic launch ceremony he organised for the 2dF instrument in 1996. An essential element in the AAT's success has always been its ability to attract and keep excellent staff; Llew was amongst the most outstanding examples. His wife Edna also deserves our very sincere thanks for her willingness to share so much of Llew's time and energies with the AAO."

"The HP-45 is the second scientific pocket calculator introduced by Hewlett-Packard, adding to the features of the HP-35. It was introduced in 1973 with an MSRP of US$395. Especially noteworthy was its pioneering addition of a shift key that gave other keys alternate functions." Wikipedia
