Some doubt has been cast of late on the value in all circumstances of dedicated X Window System terminals, but the pioneer of the concept, Mountain View, California-based Network Computing Devices Inc, is finding little resistance in its quest for OEM agreements. Having won Nokia Data Systems for Scandinavia last month, it has now secured an OEM agreement with Bull HN Information Systems, which will offer the terminals, and new ones still under development, under its own name, with its XPS and DPX/2 Unix systems. Although the Bull empire is combining its Unix interests as Bull XS, it is not clear that the five-year agreement includes Groupe Bull at this stage; no value given.
