Magnetic tape appts. for language instruction - provides audio playback and selective display of characters with microcomputer control

摘要

A magnetic tape system for use in language instruciton uses a cassette with a number of tracks relating to a number of different languages. An additional track provides character information for display. The three audio tracks are played back to a track selector (36) coupled via a preamplifier (12) and drive amplifier coupled to a loudspeaker (18). The character information is read (32) and amplified (38) to a supply a waveform generation circuit (40). The data are fed to a microcomputer (44) controlled by a switch (42). A display control stage (46) generates selection signals (50,51). ADVANTAGE - Allows different foreign languages to be recorded.
