The VAX 4000 is a discontinued family of low-end minicomputers developed and manufactured by Digital Equipment Corporation (later Compaq) using microprocessors implementing the VAX instruction set architecture (ISA). The VAX 4000 succeeded the MicroVAX family, and shipped with the OpenVMS operating system. It was the last family of low-end VAX systems, as the platform was discontinued by Compaq.
