Abstract
Abstract An educational apparatus includes a housing having a front wall with laterally spaced arrays of sensing and positioning holes and sets of letter or number display members each including one or more positioning pins and one or a pair of differently spaced and located positioning pins projecting from the rear faces of the display members, the pins being slidably engageable with respective holes. A switch matrix is located behind each hole array and is connected to the input of a calculator or message enunciating network located in the housing and having an output connected to LCD's on the housing front wall and/or to a transducer speaker in the housing. Calculator function switch buttons are located on the front wall.
