After the neuron concept was successful in a small test machine known as "Newt", in 1959 the company introduced two commercial machines based on neuron, one for the low-end and another midrange design. In 1960, the smaller design was delivered as the Ferranti Sirius, a desk-sized system for small businesses. It was an immediate success, undercutting the price of any similar design. The larger machine, the Ferranti Orion, was developed in parallel and formally announced in 1960 with the first unit shipping in 1961. A number of engineers from the Canadian office were sent to the UK to work on this machine.
