In the summer months of 1996, HP was plugging 3000s in where mainframes were serving. Jim Murphy, program manager for the mainframe replacement project, told the 3000 community that IBM mainframes from 30 years earlier were getting the boot because HP was building servers better than the Big Blue iron.
The company was finally using 3000s to do the work they were built to do. An order fulfillment system called Heart was driving every sales fulfillment. Payroll for HP in North America was also performed using MPE/iX.
1996 was a hard year for the 3000 in some places. The spots where HP's reps felt that only a Unix solution — mistakenly called an open system — would win a sale were no-3000 zones. As a separate division, GSY's 9000 group never wanted to give any ground to HP's commercial computer line. At times, 3000 sites would be encouraged to get a open computer from HP. Plenty of the mainframe replacement in HP involved HP-UX systems.
By the time the August 1996 conference gathered in Anaheim, California, Murphy had a paper in the Interex '96 proceedings. HP IT Program to Eliminate Mainframes explained to a conference full of 3000 owners and managers that it was all HP systems inside the corporate data center by May 17, 1996. The 3000 was a key element in HP's modernization.
The role of the HP 3000 in HP's mainframe elimination process is important from two perspectives. First, as the number of data centers within HP rose, the reliance on IBM-style mainframes did not: the HP 3000s carried a fair amount of the increasing processing loads. Second, as IT began rewriting IBM-based COBOL applications for the 3000 platform, many of the re-writes included moving to client/server architectures. This meant HP IT was becoming familiar with client/server as early as the late 1980s.
The Anaheim conference was notable for another big announcement. The World's Largest Poster was unfurled in the winds of a nearby high school's football field. "MPE Kicks Butt" was the slogan on those acres of paper. Inside the HP IT datacenter, the 3000 had kicked sand into the face of some of the company's most critical mainframe systems.
