FS: MFJ model # MFJ-411 Pocket Code Tutor. From the instruction manual
(included):

"The MFJ-411 Code Tutor is a microprocessor controlled device that can
help a Novice learn Morse code at up to sixty words-per-minute. This
manual contains over 500 words, names, and call signs used in amateur
radio, and a random QSO generator to simulate "on the air" contacts."

The code tutor runs on an internal 9V battery or from 12VDC from an
external source. It uses the internal speaker, or a set of stereo
headphones can be used for private listening. The unit is small, about
the size of two packs of cigarettes side by side. It is tested and
works very well. $35
