Sir George Julius made a comment in a 1932 article, which appeared in the Gippsland Times Newspaper relating his thoughts on development of the totalisator. The content of this article is made available by the National Library of Australia on its Trove website with the following details:
1932 'HOW THE AUTOMATIC TOTALISATOR WAS INVENTED', Gippsland Times (Vic. : 1861 - 1954), 7 January, p. 3. , viewed 20 May 2016, http://nla.gov.au/nla.news-article62691937
Following are comments relating to Sir George's early design philosophy and the future of totalisator design, extracted from the Gippsland Times article. The first sentence explains his original design philosophy, which was purely mechanical and resulted in two purely mechanical totalisators being built. The first was installed at Ellerslie in New Zealand, the system that was the world's first Automatic Totalisator, and a second at Gloucester Park in Perth. The J1 Ticket Issuing machine shown above, is an example of this purely mechanical design. The second paragraph indicates Sir George's change in design philosophy, to embrace electrical elements in future systems, which were incorporated in the central processing system or mainframe, as well as in the TIMs. These electrical elements are implemented in all the following TIMs in the photo gallery. During the computer era a process took place of increasingly implementing funtionality electronically resulting in TIMs with only essential mechanical components where functions cannot be performed electronically. Following are the extracts from the Gippsland Times article:
I had the idea that if electric current were employed definite action could not be guaranteed due to the permissive action of electricity as compared with positive action of a piece of machinery.Nowadays, we have a word for Sir George's words a machine in which electricity would be the connecting medium, he is talking about a Network. Additionally Sir George's words with safeguards to ensure that if there were any failure, the operator would be warned, and the ticket not issued would in the computer era be referred to as, error detection with error handling.
I soon discovered, however, that a design restricted to the use of positive mechanism would cripple development, as the machinery was very heavy and all the recording had to be centred at one spot. Attention was then directed to a machine in which electricity would be the connecting medium, but with safeguards to ensure that if there were any failure, the operator would be warned, and the ticket not issued.
Sir George also made an observation about Australian workmen, in this Gippsland Times newspaper article. Sir George's concluding statement in the article is: These machines have all been built in Australia in almost every detail, and are a tribute to the abilities of the Australian workman. This applies to complete totalisator systems, including the central processing mainframe, as well as the TIMs and display systems and as such, applies to all the Julius Tote machinery on this website. In the computer era, when Sir George was deceased, Automatic Totalisators Limited, or what later became known as ATL, used DEC (Digital Equipment Corporation) Minicomputer systems as the basis of the central processing part of the totalisator, which were manufactured in Massachusetts in the USA.

Following is an extract from an article in The West Australian newspaper dated Thursday 13 May 1915, titled THE TOTALISATOR with subtitle Most Modern Machine in Australia, which describes the new Julius Totalisator system for Gloucester Park which relates to and indirectly refers to the J1 Ticket Issuing Machines, which are in use at the mentioned "selling windows": Further, under the existing arrangements anyone purchasing a ticket on a particular horse must go to that window over which the name of that particular horse appears. With the new tote, however, which will contain six selling windows, the purchaser has only to go to that window which lies nearest to hand, or which is at the moment most easily accessible, and ask for and purchase the ticket required, - the only difference being that instead of, as at present, asking for a ticket on such and such a horse, the purchaser will tell the clerk that he wants a ticket on such and such a number, which corresponds in the race book with the name of the horse he requires to invest upon. This arrangement, under the old system, would naturally lead to some confusion, delay, and often mistakes. Under the new system, however, all such difficulties are overcome with mathematical precision. Every selling clerk is equipped with a machine, from which he may sell tickets on any one of the 28 hordes provided for. But every one of the machines works in complete sympathy with the others, and every machine is connected in a similar manner with the number registration board at the top and outside of the building. The mechanism is so adjusted that if all the machines sold in one minute at their maximum quantity, namely, 3,000 tickets not only would the ticket, be passed through to the various purchasers in that time, but throughout the operation the registration board would go on showing the increase in the number of tickets sold on each of the horses, and at the end of the minute the total number of tickets disposed of would be there for the information of the public, who would thus be made aware on the instant of the exact odds at which each horse stood.
I find the above extract particularly interesting; Here in the words of a writer in 1915, following his sentence Under the new system, however, all such difficulties are overcome with mathematical precision, he has described a real time multi user system in operation, a system which happens to be purely mechanical. A real time multi user system today, is considered the sole domain of computers. The things that get forgotten, even a behemoth machine like the Julius Tote, implemented and utilised around the world, with lifespans reaching half a century! Unfortunately they operated in clandestine environments. I find it additionally interesting to note that this activity is all taking place whilst the First World War is raging. The wheels of the Totalisator keep turning regardless! This reminds me of another example of this. During World War 2, an Automatic Totalisators Limited engineer was interred in Manila by the Japanese Army. He was allowed out on the week ends to run the totalisator!
