YouTube somehow deleted this video so I am uploading it again.
In this video we take a look at what many consider to be the ‘World’s First Laptop’ computer, the Epson HX-20. This is an interesting computer which was incredibly small and energy efficient for its time. When a ‘portable’ computer at the time was a 10kg Compact producing a 1.75kg A4 paper sized portable computer was groundbreaking.
We’ll look at this piece of computer history and attempt to fix up the barely visible LCD display. What will be the cause? Join us and find out.
