This is the Triumpf-Adler Walkstation, also called the Olivetti D33. It was likely the first laptop with a touchpad, albeit it was not capacitive, it instead registered pressure using the included stylus. This likely was also the first laptop with an active matrix color LCD, which could be removed for desktop CRT use or swapped with a thinner monochrome one. Other features included a detachable full keyboard, an internal ISA slot, very easily upgrade-able RAM, and 386 CPU+socket for a 387.
