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 WIZ-A-TRON might have been exclusively manufactured for retailer Sears. 

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.

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 in 1993 and the rare Battlestar Galactica  - an almost perfect copy of the WIZ-A-TRON.
