Last week we reported a couple of stories' worth of information about a new emulator effort for the HP 3000. This one couldn't be more different than the Stromasys Charon product that's now winning customers. We've gotten a heads-up that another Charon site will be going online to replace large HP 3000s, this one in the northeast at a financial services company.
Meanwhile, Piotr Głowacz in Poland is fronting a band of developers who are taking an open source approach -- using publically-available documents.
We did our simulator based 100 percent on publicity-available docs (which is typical for FOSS projects). We've reached the point where the simulator is running, going through the install process for MPE/iX and crashes at the very unspecified moments. As we can't provide an HPSUSAN number for testing, we're just hoping our simulator will do (and we're closer to our goal each day).
We’re still checking to see if Głowacz’ team means that they're getting closer to a non-crash startup for MPE/iX every day. It’s not clear why if they had an HPSUSAN number, it would that help in the testing.
What your community learned in 2003 was HP's help would be required to emulate PA-RISC processors capable of booting MPE/iX. There's a Processor Dependent Code routine or module that halted the Stromasys work for years. HP's intellectual property lawyers wouldn't cooperate, and the Stromasys development had to get shelved. Until 2008, when HP changed its mind.
Open source has its unique advantages. One of them is finding things available in public domain and modifying that source code to solve a problem. However, PDC has been considered a trade secret by HP. Getting documentation about PDC from a public source is going to be a tough assignment. Stromasys got the information by arranging for a top-down, official relationship with HP. That's led to an HP Worldwide Reseller agreement.
Not even the licensees of the source code for MPE/iX have those internal HP docs about PDC in PA-RISC.
In a commercial arrangement, HP's lawyers might be convinced that it's a good idea to make that data available. It's a leap of faith to imagine that arrangement taking place for an open source project. This project would be the first open source re-engineering of a processor for the HP enterprise user base.
