Palo Alto, California-based Highland Software Inc has begun volume shipments of its novel Software Store, CD-ROMs containing collections of Unix software packages and text and graphics exhibits from multiple independent software vendors. Volume 1 contains 80+ products from 36 companies. Software areas covered include system utilities, office automation, electronic publishing, graphics and visualisation, software development and mechanical CAD/CAM/CAE. Highland is circulating disks for Ultrix, HP-UX and Sparc-based systems, sending them to users, vendor sales offices and distributors. Users inset the disks into CD-ROM drives to examine, evaluate the software and can immediately buy anything what takes their fancy via password. Highland does not take orders from end-users for applications from the software vendors. The exhibits refer the customer to sales sources.
