Nintendo's 1989 handheld that started it all, rebuilt from photos of a real one down to its ghosting screen and start-up chime (turn your sound on). The switch on top turns it off and on. The cartridge is the museum's own platformer, Deci's Dash: START begins, the D-pad moves, A jumps and holding B runs. On a computer, use the arrow keys, X for A, Z for B and Enter for START. The wheels on the sides set the contrast and the volume.
