The unit has a Perkins style braille keyboard on the main body, along with the speaker, microphone, and cursor keys. A modular braille display is slotted into the bottom.

Flipping the unit over reveals the regulatory markings, along with the release for the braille display.

Pulling this lets us release the display to swap it, lighten up the unit and run without it, or even plug it into another computer. Neat!
