The President Chess is a combination of the Superstar housing, Mark VI Sensor Board and an early Julio Kaplan program, possibly a forerunner of the program which went into the Superstar 28K.
This machine was not officially released in Germany and it is unlikely to have been released in any significant numbers elsewhere. There are known to be at least some in existence. The difficulties Scisys had in developing the Sensor Board are more than enough reason to explain the termination of this project.
