The professional CD-i Touch Pad Control Unit

The CD-i 180/181/182 professional units came with a touch-panel, that works just like the Bamboo tablets to draw on. On top there was a stylus, and it could be connected to the remote control so it becomes 1 unit. Very innovative (mind you, this was developed in the eighties) - Unfortunately, this technology never made it to the consumer versions of CD-i players, but it could have been a great feature to promote CD-i with (drawing pictures, precise control for games...)
