ABSTRACT:
A teaching machine wherein an answer provided by a student in the form of a sequence of characters is displayed as each character is correctly indicated in said sequence by the student as determined by a character by character comparison of input character indications made by the student with a correct character indication sequence stored in the machine. A single character generator may be used to provide character forming signals for forming characters in a plurality of dot matrix display devices. The character generator receives input character indications from a temporary memory in which each character indication position is addressed while the character generator is providing character forming signals for the same corresponding row of all of the display devices.
