This history page contains a photograph which is one of several belonging to the photo gallery pages which are part of several pages relating to the invention of the world's first automatic totalizator in 1913 and Automatic Totalisators Limited, the company founded in 1917 to develop, manufacture and export these systems.

The Singapore Machine Room

This is an image of a photograph that was taken at the Singapore Turf Club and shows the combined adder and counter wheel display units in the Julius Tote installed there in 1926 with 16 Ticket Issuing Machines. These counter wheel units with inbuilt adders display the tickets sold on each of the runners in a race. The solitary adder/display units sitting on top of each of the two banks of them display the grand total of all the units below them.

An Automatic Totalisators Limited product promotion document titled The PREMIER (JULIUS) AUTOMATIC TOTALISATOR, has a low resolution copy of a photograph of the outside of the Singapore totalisator building on page 20. An image of this page is shown below and the Singapore Totalisator Building external view image is in the middle row of images on the right hand side. The annotation of this external view image reads: FIG. 41. Exterior of main Totalisator Building Singapore Turf Club. The Singapore Machine room shown in the image above is on the first floor of the Totalisator Building behind the indicator on display in the image below labelled FIG 41. This image makes it clear that the right hand bank of adder/display units in the image above represent the Win pool and the left hand bank represents the Place pool. This is evident from the painted text on the external view of the Singapore Tote House below, WIN twice on top of the left investment indicator and PLACE twice on top of the right investment indicator. As the outside front view below has the WIN indicator on the left, the inside rear view of this indicator shown in the image above has the WIN indicator on the right. The Win and Place pool grand total adder/display units can be seen above and central to their respective runner adder/display units in the image above. These two grand total counters can be seen in the outside view image below where they look black for some reason. Either they are in the shade or perhaps they were not in place when the exterior view of the Singapore main totalisator photograph shown in the image below was taken. In that image it is also possible to make out some of the selling windows and queueing rails on the ground floor below the indicators.

On the left hand side of the photo of the exterior of the Singapore main Totalisator Building in the image below identified as FIG. 41, is a photo of the internal view of the ground floor level of the Singapore Totalisator Building. The annotation for this internal view of the ground floor level reads: FIG. 40. Interior of the ticket selling room Singapore Turf Club Totalisator Building. This selling room is where the sixteen J5 Ticket Issuing Machines are located which are connected to the adding units upstairs shown in the image above. I deduce that these TIMs are not directly connected to the adders rather that they are connected via a front end processor. The front end processor contains Time Division Multiplexers. I come to this conclusion by the observation that the adders only have two or three escapement wheels rather than 16, one for each of the TIMs, which would be required otherwise. The front end system is required to multiplex multiple ticket issuing machines onto each of the solenoids that control the escapement mechanisms that in turn control the rotation of the escapement wheels. The investment is represented as angular displacement of the output of the adding shafts. Looking at the nearest two adder/display units in the image above, the adder part of the unit can be discerned protruding out to the right from the lower right hand end of the counter wheels. In a higher resolution copy of this image it is clear that there are at least two escapement wheels with their associated escapement mechanisms and solenoids. It seems there is an outline of a third escapement wheel. If there are only two escapement wheels, then each will support 8 machines giving a total of 16.

Additionally I have, what I thought was a photocopy of the document mentioned above, PREMIER (JULIUS) AUTOMATIC TOTALISATOR except that it has 1930 added under the title. I was surprised to find that although they both cover similar information it is presented very differently. In this photocopy, I discovered information I had not seen before. There is an image of the adder and counter wheel display unit that is used in this installation and are visible in the image at the top of this page. The poor quality of this photograph prohibits me from presenting it here.The annotation for this image reads Horse Unit of small type machine. Associated text indicates that the largest type unit has recorded over 250,000 bets per minute, the medium size records at 3000 bets per minute and the small machine at 1000 per minute. As a contrast to the Horse Unit of small type machine, you can view an image of the largest type unit as mentioned in the document, on this website.

Following is an extract from the ATL (Automatic Totalisators Limited) booklet titled The Computer Tote 1974 which relates to Singapore in the computer era, 48 years after the Julius Tote was installed. The totalisator business had changed considerably in the near half a century, going from 16 TIMs in 1926 to 256 in 1974 when this article was written! And now the extract:

The Singapore Turf Club and Automatic Totalisators Limited were associated with one another long before the computer tote was ever thought of. That association goes back as far as 1926, in the days of the T-model ford, when the club commissioned A.T.L to install its first Electro-mechanical Totalisator. As the popularity of racing in Singapore grew, so did the demands on the Club's totalisator operations and over the years additional equipment has been installed to keep its on-course betting service to the public continuously updated.

Last year, when the progressive Singapore Turf Club decided to go electronic and install a Totalisator System with a capacity to meet its rapidly growing turnover in betting it selected A.T.L's newest computer system.

The A.T.L Computer Totalisator System using two Digital Equipment Corporation PDP 11 Computers is flexible and capable of any required expansion to meet future growth.

The Singapore computer tote caters for standard betting pools, Win, Place and Forecast with a current capacity of 256 Ticket Issuing Machines.
