A quite little strange computer, which appeared under different designs...
The original model seems to be the [Rabbit Computer RX83](/museum/rabbit-computer-rx83/) announced at the 1983 CES. It looks like the computer was produced in Hong-Kong and then proposed to several companies in the rest of the world to market the computer under their own brand.
However no such computers have been found so far, maybe proving that the original company failed to produce the computer, or that it canceled the project at last minute, or that so few were sold that it's difficult to find a specimen today...
But if you look at the pictures section, you'll notice the that the computer evolved in different plastic cases. The "Charlemagne" picture, shows a case and keyboard identical to the [CCE MC1000 computer](/museum/cce-mc-1000/). This means that the project was finally marketed in Brazil, exclusively for CCE, and that the CCE MC1000 is indeed an incarnation of the GEM 1000/Rabbit Computer RX83.
