History processor heralds new Wayback/iX
A reconfiguration of HPCALENDAR intrinsic capabilities is opening the door for date revisions, one of the last remaining roadblocks to an everlasting MPE/iX lifespan. The design and development of the project has been underway in a Sourceforge repository since 2013, with a handful of volunteers working to deliver the new intrinsic WAYBACK.
Volunteers cited the work of the Stromasys Charon HPA system for providing the ongoing inspiration to keep the work alive. One developer, who requested anonymity for fear of having his report labeled fake news, said that the everlasting platform for MPE/iX software triggered the stealth project. "This is no fool's errand," he said. "We'll bring these apps into a future HP never dreamed about. That's the value of the HP Way, retaining value and profitability."
When successfully tested, WAYBACK will bypass the 2028 roadblock to date processing. The Sourceforge team, which calls itself the League of Joy, believes that an additional processor will have to be added for HP 3000 hardware manufactured by Hewlett-Packard. Emulated and virtualized HP 3000s are expected to need no such separate CPU, although a high number of cores will make date manipulation seamless.
The end of accurate date processing — a state that the League calls Fake Dates — was never a concern when MPE was first developed. "This is not a bug, really," said Vladimir Volokh, who is not a part of the League development team. "It's a limitation. This 'end of 2027' date was as far away as infinity when MPE was created." Adding a Wayback/iX to the package of Fundamental Operating System components is the next step in the work to add pages to the 3000's calendar.
HPCALENDAR, rolled out by Hewlett-Packard engineers in the late 1990s for the 6.0 release of MPE/iX, has been a newer tool to solve the old Fake Date problem. Since HPCALENDAR is fresher than CALENDAR, it's only callable in the 3000's Native Mode. WAYBACK intercepts the calls to CALENDAR and pipes them though HPCALENDAR, or so it's hoped once this history processor makes its way through beta testing.
In the meantime, one of the developers in the League of Joy suggested that IT pros who want their MPE/iX apps to run beyond 2028 should bone up on using intrinsics. Suggesting the Using Intrinsics whitepaper on the 3K Associates website, D. D. Browne predicted a swift end to the Fake Date roadblock.
"We've all been keeping the 3000's applications alive for longer than NPR has been broadcasting real news," Browne said. "It's going to carry us all beyond retirement," he said of any system running with WAYBACK. "Back in the days the 3000 was built, TV and radio stations once signed off the air. This operating environment is never going off the air."
