ZX80 character set : ウィキペディア英語版 | ZX80 character set The ZX80 character set is the character encoding used by the Sinclair Research ZX80 microcomputer and its successor, the ZX-81. The encoding is notable for having no relationship with the more common character encodings ASCII and EBCDIC available at the time of its inception. The encoding is small enough to fit the character codes into a single byte. In fact, only 64 characters are present in the encoding. By setting the most significant bit of a particular character to 1, an inverted character glyph is obtained. The small effective range of code points (0-63, inclusive) precludes support for latin lower case letters, or symbols used widely in computing such as the exclamation point or the at sign. Block elements figure prominently in its limited repertoire, as these -- combined with the inverse graphics capability -- made support of 64x44 pixel graphics possible. In the Sinclair ZX Spectrum, the successor of the ZX-81, this character encoding was abandoned in favour of the ZX Spectrum character set, which is a derivative of ASCII. ==Layout==
