Manufacturing companies using HP 3000s had license to customize. Many of the MANMAN customers held licenses that gave them source code to the ERP-MRP software for MPE. MM II, from HP, even had a specific toolset called the Customizer. There are so many ways a business process can differ from company to company that these mods, short for modifications, felt essential at the time.
Times change, and the current era is urging some manufacturing companies off HP 3000 hardware. In some cases the firms have retrenched and moved out of Hewlett-Packard's hardware limitations. Stromasys Charon had its evaluation at Magicaire, one of the companies allied to Carrier. One advantage of virtualization of ERP systems: it permits a company to hold onto their mods. The business software built over several decades remains intact.
Moving away from solutions based on MPE/iX forces a hard look at mods. When you need to keep them all, or even a lot of them, you need to hire wizards who have access to time machines, it seems. One expert shared the reality of being a part of the Mod Squad in 2017, caring for software built in the 1990s. MANMAN is capable of a great deal of uncharted magic, built from the foundations of ASK Systems app suite.
"Some people who asked for these mods have been gone for over 10 years," our expert said. "I can't imagine converting Ed Stein to another system—his mods are very cool. No package is going to be able to duplicate them out of the box. Some incredibly sophisticated stuff was done to MANMAN after it left ASK's hands."
So while it's not impossible to find the way to carry mods into the future, a Mod Squad expert needs patience and fortitude and a respect for how the 3000 ERP systems got things done. Without that, there's even more disruption and delay, as migrators will struggle to understand the inherent magic of MANMAN.
