The Sol-20 was the first fully assembled microcomputer with a built-in keyboard and television output, what would later be known as a home computer. The design was a combination of an Intel 8080-based motherboard, a VDM-1 graphics card, the 3P+S I/O card to drive a keyboard, and circuitry to connect to a cassette deck for program storage. Additional expansion was available via five S-100 bus slots at the back of the machine. It also included swappable ROMs with a rudimentary operating system.

  • I Sol Terminal Computer sono una linea di personal computer basati sul microprocessore Intel 8080 e sul bus S-100 prodotti dal 1976 al 1979 da Processor Technology. Rispetto ad altre macchine dell'epoca, come l'Altair 8800, i computer Sol erano venduti già pronti all'uso, offrendo tutti i componenti necessari al loro funzionamento: il modello Sol-20 è infatti il primo computer venduto con tastiera e video integrati, una tipologia costruttiva che diverrà in seguito uno standard con l'uscita del Commodore PET e dell'Apple II.

  • Sol-20(ソル20)は、プロセッサ・テクノロジーが開発・販売したマイクロコンピュータである。キーボードとテレビ出力を内蔵し、組み立て済み製品として販売された世界初のコンピュータで、このようなコンピュータは後にホームコンピュータと呼ばれるようになる。 設計は、Intel 8080ベースのマザーボード、グラフィックスカード・、キーボードを駆動する入出力カード・、プログラム保存用のカセットデッキに接続する回路を組み合わせたものだった。マシンの背面にある5つのS-100バススロットを介して追加の拡張が可能だった。また、初歩的なオペレーティングシステムを同梱した交換可能なROMカートリッジが含まれている。 Sol-20は1979年まで生産され、その時点で約12,000台が販売された。その頃までには、「1977年の三位一体」と呼ばれたApple II、PET 2001、TRS-80が市場を席巻していた。プロセッサ・テクノロジー社は、新製品の導入に続けて失敗したことにより、倒産に追い込まれた。フェルゼンスタインは後に、同じ基本設計によるポータブルコンピュータ・Osborne 1を開発し、成功を収めた。 (ja)
