VAX 4000

The VAX 4000 series was a series of VAX minicomputer systems. They were introduced in 1990 as replacements/upgrades for the MicroVAX 3100 series. In all members, disk mass storage was supported using the DSSI bus, a built-in on-board Ethernet interface was provided, and general I/O used the QBUS.

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.

The models in the series were:

The VAXserver 4000 series is a related category using the same hardware base; the VAXstation 4000 series apparently shares only the name.
