- The Eclipse MV/8000 was the first in a family of 32-bit minicomputers produced by Data General during the 1980s. Codenamed Eagle during development, its architecture was a new 32-bit design backward compatible with the previous 16-bit Eclipse series. The development of the computer and the people who worked on it were the subject of Tracy Kidder's book The Soul of a New Machine. The MV/8000 was succeeded by the MV/6000, MV/8000-II, MV/2000, MV/2500, MV/4000, MV/10000, MV15000, MV/20000, MV/30000 and MV/40000. Later models such as the MV/40000 were SMP systems with hot-swappable components. The Eclipse MV was a 32-bit CISC architecture with a 4 GB address space. The 4 GB address space was divided into eight rings of 512 MB each with a privilege mechanism mapped onto the rings. The outermost ring, ring-7, was the least privileged. The inner-most ring, ring-0, was the most privileged. The AOS/VS operating system supported the notion of lightweight "tasks" as well as processes. A single process could start various tasks that would all share a global address space (similar to modern "threads"). Tasks were very easy to use from Data General's FORTRAN compiler, and allowed faster context switching than using full processes. One could also start subtasks, using so-called "Son" batch process. This was done using the CLI (Command Line Interpreter). It resulted (de facto) in an online batch process. This process would, however be killed as soon as the user would log-off. The MV/8000 had only two "true" batch processes, as not to frustrate the online processes. The "plus" of the online batches was that they ran with the same priority as the normal online processes.

- Eclipse MV/8000 (エクリプス・エムヴィ8000) は、1980年代にデータゼネラルによって作られた32ビットのミニコンピューターの最初のファミリーである。開発中はイーグルというコード名で呼ばれ、そのアーキテクチャは新しい32ビットの設計で、以前の16ビットのエクリプス・シリーズと後方互換性を有した。このコンピューターおよびその開発に取り組んだ人々は、トレイシー・キダーの本『超マシン誕生』"The Soul of a New Machine" の主題である。MV/8000の後には MV/8000-II、MV/2000、MV/2500、MV/4000、MV/10000、MV15000、MV/20000、MV/30000および MV/40000が続いた。後のMV/40000のようなモデルは稼働中に部品を交換できる対称型マルチプロセッシング(SMP)システムであった。 エクリプス MVは、4GBのアドレス空間を備えた32ビットのCISCアーキテクチャである。4GBのアドレス空間は 512MBの8つのリングに各々分割され、特権メカニズムはそのリング上に写像された。最も外側のリング(リング7)は最も少ない特権が与えられ、最も内側のリング(リング0)は最も多くの特権を与えられた。AOS/VSオペレーティングシステムは、ライトウェイト「タスク」とプロセスの概念をサポートしていた。1つのプロセスで、全てのグローバルアドレス空間を共有するさまざまなタスクを開始できた(近年の「スレッド」と同様)。 タスクは、Data GeneralのFORTRANコンパイラから極めて使いやすく、完全なプロセスを使用するよりも高速なコンテキストスイッチを可能とした。いわゆる「Son」バッチプロセスを使用してサブタスクを開始することができた。これは、CLI(コマンドラインインタプリタ)を使用して行われた。その結果は、(事実上の)オンラインバッチプロセスであった。ただしこのプロセスは、ユーザーがログオフするとすぐに強制終了された。MV/8000には、オンラインプロセスを妨げないように、2つの「真の」バッチプロセスしかなかった。オンラインバッチの利益は、通常のオンラインプロセスと同じ優先順位で実行されることだった。 (ja)
- Il Data General Eclipse MV/8000 è il primo modello della famiglia di minicomputer a 32-bit prodotti dalla nell'anno 1980. Il suo nome in codice durante lo sviluppo è Eagle e la sua architettura è un'estensione di quella già usata nella serie a 16-bit. Dopo il MV/8000 si sono succeduti i modelli MV/8000-II, MV/2000, MV/2500, MV/4000, MV/10000, MV15000, MV/20000, MV/30000 e MV/40000. Gli ultimi modelli come il MV/40000 sono sistemi SMP con componenti sostituibili a caldo (Hot-Swappable). L'Eclipse MV è dotato di un'architettura CISC a 32-bit con uno spazio di memoria indirizzabile di 4 GB. I 4 GB sono divisi in 8 anelli da 512 MB ognuno con un meccanismo di privilegio d'accesso mappato dentro l'anello. L'anello più esterno, il ring-7, è quello meno privilegiato. Quello più interno, il ring-0, è quello più privilegiato. Lo sviluppo del computer e il personale che ci ha lavorato sono oggetto del libro (The Soul of a New Machine, 1981) di , vincitore del Premio Pulitzer per la saggistica e del National Book Award per la saggistica.
