The DECstation was a family of MIPS-based computers built by DEC beginning in 1989. They ran Ultrix, which was a variation of UNIX.The DECstation 2100/3100, released in 1989, was the first commercially available RISC-based machine. At the time DEC was mostly known for their CISC systems including the successful PDP and VAX lines. The DECstation 3100 was the world's fastest UNIX workstation at the time.
The DECstation name was originally used for word processing systems based on the PDP-8. These
systems, built into a VT-52 terminal, were also known as a VT-78 .
