Spaceships that repair themselves automatically don't exist. And they won't in the future either. The CD- ROM "Rado Z" offers star voyagers the possibility of assistance in both word and deed, which is quite fortunate because spaceship "Rado Z" is quite battered at the beginning. Complicated technical problems are solved in a playful manner, encouraging concentration and powers of deduction. A professionally designed CD-ROM for children from 9 to 99.
