Emulation or iron meets Classic 3000 needs
A few weeks ago the 3000 community was polled for a legendary box. One of the most senior editions of Classic 3000s, a Series 42, came up on the Cypress Technology Wanted to Buy list. The 42 was the first 3000 to be adopted in widespread swaths of the business world. It's not easy to imagine what a serious computing manager would need from a Series 42, considering the server was introduced 35 years ago.
These Classic 3000s, the pre-RISC generation, sparked enough business to lead HP to create the Precision RISC architecture that was first realized with its Unix server. The HP 9000 hit the Hewlett-Packard customer base and 3000 owners more than a year before the 3000's RISC servers shipped. Without the success of the Classic 3000s, though, nobody could have bought such a replacement Unix server for MPE V. Applications drive platform decisions, and creating RISC had a sting embedded for the less-popular MPE. Unix apps and databases had more vendors.
That need for a Series 42 seems specific, as if there's a component inside that can fulfill a requirement. But if it's a need for an MPE V system, an emulator for the Classic 3000s continues to rise. Last week the volunteers who've created an MPE V simulator announced a new version. The seventh release of the HP 3000 Series III simulator is now available from the Computer History Simulation Project (SIMH) site.
The SIMH software will not replace a production HP 3000 that's still serving in the field, or even be able to step in for an archival 3000. That's a job for the Stromasys Charon HPA virtualized server. But the SIMH software includes a preconfigured MPE-V/R disc image. MPE V isn't a license-protected product like MPE/iX.
Software like Charon, and to a lesser extent SIMH, earns its consideration more easily than old iron. Virtualization is so embedded in IT plans that it's a bit of a ding to admit you don't virtualize somewhere.
The deep-in the-mists tech of the ATC terminals is a big part of the new SIMH. The new capability shows off the limitations that make it obvious why PA-RISC 3000s are still genuine data processing solutions. The SIMH terminal IO uploads via Telnet using a Reflection terminal emulator are now over 100 times faster than earlier releases of the MPE V software. As a reminder of the IT world's pace during the 1980s when MPE V was king, the new, faster upload time for a one-megabyte file has decreased from 69 minutes to 30 seconds.
That's still a 2-MB a minute pace. A Simulator's User Guide shows the way for ATC setup required for successful Reflection Transfers. That's from the era when locating a Reflection client program on a 3000 was essential for moving data in many applications. That was also the era when HP was manufacturing its own disc drives in Boise, Idaho. The burn-in testing for those drives up in that factory was powered by a massive row of Series 42s. My 1988 tour at Boise was the last time I saw a Series 42 in use.
