The
WIZ-A-TRON was introduced soon after the rare MATH MAGIC.
The only difference is the design of the keyboard plate, from the technology
both toys are identical.
The beautiful WIZ-A-TRON is a variation of the Little Professor. The Little Professor gives you one of ten-thousands pre-programmed math questions and you have to type the correct answer. The WIZ-A-TRON works different: You have to type the question and the answer ! The wizard gives you only a correct or wrong answer.
Dismantling
the WIZ-A-TRON reveals an internal construction already known from the Little
Professor. The only differences are a missing sliding switch and another
software programmed into the single-chip calculator circuit.
Similar educational products are known from National
Semiconductor with the Quiz-Kid and Radio Shack with the wonderful
Monkey See.
Both use simple green and red indicators to state correct and wrong.
Don't miss the similar Mickey Math Adventure
introduced later.
