PRODUCTION HISTORY
Early in 1983, Mattel Electronics created an Educational Products department to develop educational game ideas, primarily for the Entertainment Computer System.
Number Jumble was one of the ideas that came out of that department. Others that went into production were Jetsons' Ways With Words and Flintstones Keyboard Fun.
The game was completed late in 1983. Packaging reached the black & white mockup stage, but Mattel Electronics was closed before the game could be released.
Although designed for the Entertainment Computer System, the game was played with the hand controllers. The ECS keyboard was only used if the player needed to do scratchpad calculations before entering answers.
