A terminal

The story of Solitaire on Microsoft Windows actually starts rather earlier, back in the fall of 1979. The student Brodie Lockard, a gymnast for Stanford, had an injury during practice on a trampoline, landing on his neck and damaging his spinal cord. He became paralyzed from the neck down permanently at the age of 19.
While in the hospital, he was able to use a pen in his mouth to draw pictures (his first being of a boy in a wheelchair); relatedly, he later requested a PLATO terminal.
PLATO was, essentially, a networked system far ahead of its time, a full graphical system from 1960 with touch screens, and the spawning point for the world's first CRPGs and first-person shooters. It spawned from the University of Illinois, but, significantly, had a foothold in Stanford by the time Lockard was a student. He was able to get a special hookup for his long-term stay in a hospital that he could manipulate with an electronic pen.
