French software house Groupe Prologue SA is one of those companies that looked to have been left without a future once Microsoft Corp revealed its plans for a multi-user version of Windows NT back in March (CI No 3,112). Now the company has agreed to acquire Campbell, California-based GraphOn Inc, a $3m turnover thin-client and X-server company with close links to Sun Microsystems. The acquisition will take place through Prologue’s recently formed Prologue North America subsidiary, which currently has around 10 staff. GraphOn will become a wholly-owned autonomous subsidiary to the French company, and will be run by GraphOn president Walter Keller. Terms of the deal were not revealed. Fifteen year-old GraphOn, which has concentrated on the Unix marketplace, won Sun as the first licensee of its Go-Joe thin-client software in July (CI No 3,193), and says there are more announcements to come. The product provides Unix and X Window application access from Java-enabled desktops, including browsers such as Internet Explorer and Netscape Navigator. The company also has a PC X-Server product. Prologue is one of only two companies that has licensing agreements with Microsoft to develop multi-user extensions for Windows NT. The other is Citrix Systems Inc.
