ICL’s journey to produce the Comet computer series was long. At the beginning the company announced that they had joined forces with the HH Production (later known CubeTech). The collaboration was brief and they broke off the partnership. HH Electronic developed the next Comet based on their own MPS system. Large scale production was attempted, but failed miserably.

The main designing engineer of ICL parted ways and produced himself the successor of the Comet series. The same applied to HH Production, though. The history of production is complicated. Bottom line, they were the preferred machines for educational use during 1970s and 1980s. Prime rival was the Piccoline Calculator.

That was just a snapshot on the presentation of the techmuseum series. Indulge more into the history. Continue reading more about the present model, the ICL MPS 3000 here. Alternatively, find more exciting stories like this one here.
