翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク List of early microcomputers ： ウィキペディア英語版 List of early microcomputers This is a list of early microcomputers sold to hobbyists and developers. These microcomputers were often sold as "DIY" kits or pre-built machines in relatively small numbers in the mid-1970s. These systems were primarily used for teaching the use of microprocessors and supporting peripheral devices, and unlike home computers were rarely used with pre-written application software. Most early micros came without alphanumeric keyboards or displays, which had to be provided by the user. RAM was quite small in the unexpanded systems (a few hundred bytes to a few kilobytes). By 1976 the number of pre-assembled machines was growing, and the 1977 introduction of the "Trinity" of Commodore PET, TRS-80 and Apple II generally marks the end of the "early" microcomputer era, and the advent of the consumer home computer era that followed. ==Discrete logic== Before the advent of microprocessors, it was possible to build small computers using small-scale integrated circuits (ICs), where each IC contained only a few logic gates or flip-flops. * The Kenbak-1 (1971) used discrete transistor-transistor logic ICs and had 256 bytes of memory. It was priced at USD 750 and sold only 40 units.〔p. 4/3, ''A history of the personal computer: the people and the technology'', Roy A. Allan, 2001, ISBN 0-9689108-0-7.〕 * The Educ-8 (1975) was an Electronics Australia magazine project describing a computer built from TTL ICs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of early microcomputers」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
