NLS/BPH Digital Talking Book Cartridge and Player

prototype digital talking book and cartridge

The cartridge shipping container is slightly longer and wider than a green cassette box but only half the thickness. The color will not necessarily be blue, despite the photo.

The cartridge itself is the size of a cassette, but with a more complex shape. The end of the cartridge with the round finger hole is slightly thicker than a cassette, with square sides, but is also bevelled, so that when that end of the cartridge is pressed down on a flat surface in front of the player, the other end of the cartridge, with the USB connector, tilts up and can slide smoothly into the player. The end of the cartridge with the USB connector is also bevelled, but with the bevels slanting toward the center of the cartridge, so that there is only one way it will fit into the player. The USB connector is barely visible in the picture of the open mailing container.
