The Epson HX-20 (also known as the HC-20) was the first “true” laptop computer. It was invented in July 1980 by Yukio Yokozawa, who worked for Suwa Seikosha, a branch of Japanese company Seiko (now Seiko Epson), receiving a patent for the invention.

I’ve got three of these, pity the batteries leak THROUGH the wires and end up corroding stuff on the board.
Fun little novelties but not very practical do do anything with these days. Maybe I’ll write a small program to turn it into a keyboard…
The keyboard does look very nice, good luck with that!
