McLean, Virginia-based Excalibur Technologies Corp, profiled here in April (CI No 1,908), duly launched versions of its flagship PixTex/EFS document imaging and retrieval software for Sun Microsystems Inc, Hewlett-Packard Co and IBM Corp RS/6000 Unix workstations. The Sun version will ship in October, to be followed sometime later by releases for the Hewlett-Packard and IBM systems. First customer shipments are to include workstation applications as well as support for personal computer and Macintosh clients. Excalibur also announced its Apple Computer Inc Macintosh client for Digital Equipment Corp VMS systems. The Macintosh client and the Windows client will ship for the Sun, Hewlett-Packard and IBM RS/6000 version in the fourth quarter. By the end of the year, the company says, PixTex/EFS will be available in all major workstation, client-server, and networked environments. PixTex/EFS, as reported, is currently available on DEC workstations, in the stand-alone and client-server versions. Prices for PixTex/EFS on the afore-mentioned Unix systems will range from $20,000 for the stand-alone versions to $77,000 for unlimited-use server versions. As detailed back in April, PixTex/EFS is based on Excalibur’s proprietary pattern recognition technology, which provides automatic indexing and content-based retrieval facilities.
