Epson HX-20

HX-20

 Superbly designed and engineered, the Epson HX-20 can be considered as the first true portable computer. It was the only package available at the time which included a micro cassette drive, a mini-printer and a LCD display.

The small built-in printer could print graphics or text (up to 24 columns, 47 lines per minute). The small tape recorder was pretty fast (considering it was a tape drive).


Computer would rewinds or fast forwards the tape automatically to find the right file. This tape recorder could be removed and replaced with a ROM cartridge.

Two case colors were released, cream and silver. To our knowledge, the silver version was mainly intended for the German market.
