-The '''VAX 4000 series''' was a series of [[VAX]] [[minicomputer]] systems. They were introduced in 1990 as an upgraded alternative to the [[MicroVAX 3100 series]]. In all members, [[disk]] [[mass storage]] was supported using the [[Digital Storage Systems Interconnect|DSSI]] [[bus]], a built-in on-board [[Ethernet]] interface was provided, and general [[input/output|I/O]] used the [[QBUS]].

In all members, a built-in on-board [[Ethernet]] interface was provided (similar to the 3100's); [[disk]] [[mass storage]] was supported using the [[Digital Storage Systems Interconnect|DSSI]] [[bus]], and general [[input/output|I/O]] used a [[QBUS]] (differences to the 3100's).
-The lowest models were built around the [[KA650 CPU]], and later the [[KA655 CPU]] and the [[KA660 CPU]], which all used the [[KA650 Main Memory System]]. Later models were built around the [[KA670 CPU]], which used the [[KA670 Main Memory System]]. Final models were built around the [[KA675 CPU]], [[KA680 CPU]], and [[KA690 CPU]] which all used the [[KA690 Main Memory System]].
+Two ranges exist within the family: in the upper range, [[main memory]] was carried on [[DEC card form factor|quad]] cards which used a specialized interface to the [[Central Processing Unit|CPU]], and tower packaging was used; in the lower range, [[Single Inline Memory Module|SIMM]] memory was used, and the system was carried in a desktop package.
