Produced by Centurion Industries Ltd in 1974, the ‘Digitor Learning Arithmetic Module’ was one of the first uses of a microprocessor for an educational device. In simple language it was a very basic electronic game where children could be tested on their knowledge of simple addition, subtraction, multiplication and division. If you get it right you received a smiley face, get it wrong and you get a sad face! Although wonderfully primitive compared to modern educational maths devices, my 9 year old still found it very engaging and I like the Space Age design.
Although lots of these were reputedly sold, they are surprisingly rare today and this is the first one I’ve seen for a few years (I know, you’ll all tell me now how you have one in the attic). I picked it up from a fair here in the UK and while it is sadly not entirely complete it does work fine and will be fun for some collector I’m sure. It is missing its black plastic round feet and its left hand dial (which I believe adjusted it’s difficulty level). The dial on the right determines how many questions you will get asked and the machine will keep re-asking you the same sum until you get it correct (my kind of game!). The on/off switch on this example is a little temperamental but works. Importantly the case and legs seem to be in pretty decent original condition. The parts that are missing are just simple black plastic so could be made up with a 3d printer very easily.
This example is intended for 240v.
Dimensions: 17 cm wide x 17 cm deep x 25 cm high.
