Dave Cutler

Dave Cutler (born March 13, 1942) is a noted software engineer, designer and developer of several operating systems including the RSX-11, VMS and VAXELN systems of Digital Equipment Corporation and Windows NT from Microsoft.

Prism and Emerald projects

DIGITAL began working on RISC technology in 1986 and Cutler, who was then working in DEC's Seattle facility, was elected to head Prism, a project to develop the company’s RISC machine. Its operating system, code named Emerald, would embody the next generation of design principles and have a compatibility layer for UNIX and VMS. The RISC machine was to be based on ECL technology and was one of three ECL projects DIGITAL was undertaking at the time. On the basis of the R&D cost involved in funding multiple ECL projects to yield products that would ultimately compete against each other, Prism was cancelled in 1988 in favor of a system running Ultrix on processors produced by MIPS. Of the three ECL projects, the VAX 9000 was the only one that was commercialised...
