Seven screws hold in the keyboard itself, and once these are removed the board can be lifted free.

Flipping the board over reveals an interesting mix of switches. The braille dots are linear Cherry ML switches (also used on BrailleNote devices), but other buttons are conductive pads embedded into a rubber dome sheet.

The Cherry MLs would typically have a linear feel, but the dome sheet gives them a squidgy quasi-tactility. Funky!
