The latest version of the GoldWorks expert system building toolkit was also launched in London last week by Watford-based Artificial Intelligence Ltd, the UK distributors for Gold Hill Computers Inc, Cambridge, Massachusetts. GoldWorks II has been designed to enable the development of advanced applications and incorporates a set of new features, including support for Microsoft Windows, a graphics layout tool, and browsers to provide a visual representation of the frames and rules in the expert system. In addition, Goldworks II offers the combination of Full Common Lisp with C, which provides comprehensive rule and frame definition ability. First out is the MS-DOS version at the beginning of 1989, costing UKP5,500, but versions for the Apple Macintosh II and the Sun Microsystems workstation families are promised later in the year, and a DEC VAX edition is to be announced in the near future. Gold Hill says that as yet it has no plans for a version for the Mac’s A/UX Unix.
