In the manual of the original CD-i Touchpad (the Gravis gamepad version, with the joystick on the D-pad) it is stated it is design specific for use witth the CD-i 2xx players. I wonder why they specifically mention it like this, as I suppose the touchpad can in general be used on any CD-i player! It was at the time (1991-1992) of course that in Europe we only had the 205, 210 and 220 as consumer models, perhaps that's why they made this reservation.
