Siemens Nixdorf Informationssysteme AG has signed a joint technology pact with VMark Software Inc that will have it collaborating on the further development of VMark’s Pick-under-Unix uniVerse software and accelerating the Natick, Massachusetts company’s research and development plans. The German is of course interested in the stuff because of its purchase two years ago of Intertechnique Informatique SA, the long-time French Pick merchant with 7,000 installations, now absorbed into the Teuton and peddling Nixdorf’s Targon machines. The initial products stemming from this agreement are planned for fourth quarter release and will include a Motif interface for uniVerse and client-server products that put Motif on applications running in ASCII terminals, X-terminals, personal computers running Windows 3.0, and Apple Computer Inc Macintoshes. The pair will also work on tools to facilitate the development of X Window-based applications. VMark expects to do versions of anything the two develop for all its supported hardware systems, and it has just cut a pre-paid royalty agreement with Pick Systems Inc that frees it from any further royalty commitment.
