The VAXserver was a family of minicomputers developed and manufactured by Digital Equipment Corporation (DEC) using processors implementing the VAX instruction set architecture (ISA). The VAXserver models were variants of various VAX-based computers which were configured to only run operating systems which were licensed for network server use and not interactive time-sharing use.^[1][2] This was accomplished with different CPU modules and firmware.
