Epson HX-20

Epson · 1982

Arguably the first true notebook computer: a full keyboard, a four-line LCD, a microcassette drive and a printer all in something the size of an A4 pad, with fifty hours of battery life, in 1982. It defined what portable computing could be and remains an impressive object.
