Intergraph Corp, Huntsville, Alabama has split its software operation and hardware unit to create two internal divisions, in an effort to make the units’ business activities appear more autonomous to the outside world and to be able to sell products separately. Now there is Intergraph Software Solutions, responsible for applications and systems software, under newly-named president Tommy Steele, and Intergraph Computer Systems, the hardware arm, under vice-president John Thorington. Steele and Thorington, both Intergraph veterans, report directly to Intergraph chief Jim Medlock. Intergraph Software Solutions, acknowledged to be the largest NT development site in the world, estimates it now has 150 of the roughly 300 packages it intends to convert to NT, ready. Although Intergraph has 1,200 packages altogether, the balance of these will not make the jump from Unix to NT. This week at Windows World in Dallas, Intergraph is to announce Daytona versions of its PC-NFS and Diskshare Unix-NT interoperability products developed in concert with SunSoft Inc. More than 50% of the efforts of Intergraph’s hardware arm are NT-directed. In addition, Intergraph has released its promised NT-to-Unix interoperability packages. It has tuned up and repackaged its PC-NFS and DiskShare programs and released an X Window System server for NT which enables NT nodes to emulate an X Window terminal in order to run X-based applications on Unix servers. PC-NFS 2.0, which connects an NT system to Unix Network File System servers, is revamped with an NT version of the Telnet and File Transfer Protocol packages found in the Sun’s PC-NFS which was jointly developed with SunSoft, rights for the NT version which SunSoft then gave to Intergraph. PC-NFS is $1,950 for a five-user pack. The eXalt X server for NT is $500.
