The StudyBox,
released by Fukutake Publishing Co, Ltd., was much
like a tape player for the Famicom. The accessory
was small enough to fit on top of the Famicom, to
plug into the connector. Also like a tape player,
the top of the StudyBox would open to reveal the
compartment where tapes were played.

The StudyBox plays educational tapes through your
Famicom.
The StudyBox itself did not have the standard Play,
Stop, Pause, Fast Forward and Rewind buttons on the
system, as would be expected with a tape player.
Instead, the student (presumably) would use the
Famicom controller and on-screen cues to play the
tapes.

Some of the tapes for the StudyBox.
We don't exactly know what the tapes would do. The
purpose of the StudyBox was to make the Famicom more
education, giving students the ability to learn
about whatever information was contained on the
tapes. The tapes were, of course, only sound and
voice, without visuals to accompany the studying.
