(Several different VAX microprocessor implementations were used, over the life of the series.) Although they all had some [[input/output|I/O]] [[peripheral]] upgrades available, the list is limited; the 3100 was not built around a standard [[bus]]. Although technically available for interactive [[time-sharing]] usage (as a [[minicomputer]]), the standard inclusion of a [[display]], [[keyboard]] and [[mouse]] on them indicates that they were primarily geared toward use as a [[personal computer]] (in the generic sense).
