Epson<\/span> HX-20 <\/span>(znano i kao HC-20) bilo je prvo \u201epravo\u201c prijenosno ra\u010dunalo.

Bilo je programirano na EPSON BASIC jezik, a memorija mu je mogla podnijeti od 16 <\/span>kB<\/span> do 32 <\/span>kB<\/span>.<\/span> Pri radu je proizvodilo zvuk \u201e<\/span>biptanja<\/span>\u201c. Za \u0161to lak\u0161i prijenos, bilo je spremljeno u odgovaraju\u0107u aktovku.<\/span>\u00a0<\/span><\/p>\n

u studenom je u Japanu bilo najavljeno kao HC-20, a u Sjevernoj Americi ga je <\/span>Epson<\/span>, na ra\u010dunalnoj izlo\u017ebi COMDEX u Las <\/span>Vegasu<\/span>, predstavio kao HX-20. Zbog svoje lake prenosivosti, <\/span>pu\u0161teno<\/span> je na masovno tr\u017ei\u0161te ve\u0107<\/span> u srpnju 1982. Vrhunac proizvodnje <\/span>Epson<\/span> HX-20 ra\u010dunalo je dostiglo 1985. i u tom periodu ih se prodalo oko 250,000 primjeraka. Ra\u010dunalo je bilo dostupno u dvije boje, a cijena jednog primjerka ovog prijenosnog ra\u010dunala iznosila je US$795 (dana\u0161njih US$2,000). Smatra se da je ovo prvo ra\u010dunalo \u010dija je prodaja napredovala i s godinama proizvodnje.<\/span><\/li>\n
proizvodnja HX-20 ra\u010dunala je obustavljena zbog dolaska bolje opremljenih prijenosnih ra\u010dunala na masovno tr\u017ei\u0161te.<\/span><\/li>\n<\/ol>\n
