The First Laptop
Posted in Retro
The first laptop computer is considered to be the Epson HX-20. The HX-20 was announced in November 1981 and started selling to the public in 1983.
The HX-20 had a 120 × 32-pixel LCD (liquid crystal display) screen. The laptop boasted 16kb (kilobytes) RAM (random access memory) which could be upgraded to 32 kb, where as most of todays laptops have at least 1G (gigbyte), a gigabyte is a million kilobytes.
It had a build-in microcassette drive, functioned on a propriety operating system and was powered by rechargable ni-cad (nickel cadmium) batteries. The batteries provided about 50 hrs of use. People who still have the HX-20, theses days have trouble with charging the batteries.
The lap top weighed 1.6 kg. It had an external floppy disk drive, an accoustic coupler and a speech synthesis device.
These ancient laptops can fetch a high price amongst collectors. I wonder if I would be able to find one of these pieces of history in the collectors items section of the classifieds. I think I’d rather buy a laptop that’s a bit more hi-tech, but the HX-20 might be something cool to have when I have a little more cash to burn.
