dismessi, in grado di eseguire l\u2019insieme di istruzioni macchina Virtual Address eXtension (VAX), sviluppati e progettati a partire dal 1976 da Digital Equipment Corporation (DEC). Oltre ad essere potenti di per s\u00e9, queste macchine offrivano anche la possibilit\u00e0 aggiuntiva di eseguire il codice PDP-11 in user mode (quindi il -11 in VAX-11), rendendo disponibile la compatibilit\u00e0 verso i nuovi modelli.<\/p><p><br><\/p><p>Il primo esemplare fu il VAX-11\/780, annunciato nell\u2019ottobre del 1977. I concorrenti nell\u2019ambito dei minicomputer, come Data General e Hewlett-Packard, non furono in grado di rispondere con successo all\u2019introduzione e al rapido aggiornamento del design VAX. DEC cre\u00f2 poi modelli sempre pi\u00f9 economici, come i 11\/750, 11\/730 e 11\/725 nel 1982. Esemplari pi\u00f9 potenti, inizialmente noti come VAX-11\/790 e VAX-11 \/795, furono invece ribattezzate serie VAX 8600.<\/p><p><br><\/p><p>La linea VAX-11 venne abbandonata nel 1988, soppiantata
