Meeting at Building D: the rarest 3000 link-up
Notices were posted this week on the 3000-L mailing list about a rare meeting next Monday, Oct. 3. At opening time 11:30, people who know and remember the 3000 will gather at The Duke of Edinburgh pub. It's a site popular enough with the MPE crowd that it's still called Building D by some seasoned community members. The Duke is on Wolfe Road, just to the west of where the 3000 grew up. As the 3000 group intends to arrive at opening time, it might be able to commandeer the snug (above).
In-person meetings for the 3000 community happen in bars and pubs by now. The last one we heard about this public was SIG-BAR's meeting in London in 2014. Dave Wiseman, a vendor and software maven whose history includes a software project called Millware for 3000s, set up SIG-BAR. The 2014 meeting was announced so far in advance that people were able to plan their summer vacations around a gathering at Dirty Dick's. There's something about English pubs that attracts the 3000 crowd.
The Duke of Edinburgh is within walking distance of a mecca of the 3000 world, now departed: The HP Cupertino campus. Building 48 has been replaced by the rising concrete and steel of the new Apple world headquarters building. There's no word yet if the 3000 friends who meet Monday at Building D will bring their drones to take their tour of the Apple-ized HP campus.
A walk through the HP parking lot and across a cozy margin of poplars used to bring you to the Duke. "It's right across the street from where MPE lived," said Stan Sieler of Allegro while announcing the meeting. As of Monday, MPE's heart will be among the taps and chips of The Duke. Two years ago, Robelle's Bob Green said this about the last in-person meeting at that London pub:
We exchanged notes on the current state of the machine—especially the new emulator—- and discovered what each of us was doing. An amazing number of people are still doing the same thing: helping customers with their IT concerns. But in reality, most of the time was spent swapping war stories from the past, which was great fun.
As for that emulator, Charon HPA is in full swing by now, a certainty of life going forward with MPE/iX systems. For one additional lunchtime, a pub will be emulating the home of the system, even as it continues to move into a virtual existence.

3000-L connects again after a silence
As if on cue after our report about its silence, the 3000-L mailing list and newsgroup sprang back to life over the weekend. One problem solved by the 415 readers was how to identify if a store to disk backup is a LZW compressed backup file. A Tracy Johnson report also confirmed that a LISTF,2 can report the time of each LISTF, by writing a specialized job.
Meanwhile, a 15-year-old HP 3000 with network connection troubles got advice from the newsgroup's readers. A Series 969 running MPE/iX 6.0 would not be the first thing you'd choose for interfacing to an internal website. But when a 3000 has data that a user needs over the Web, the server is the place to go.
Trouble started to surface when clients access a webpage which then opens a telnet session with the 3000, grabs the info, and then returns the data to the webpage.
We’ve been getting more and more errors over the last year, culminating in non-stop Could not initialize data in path with TCP, which then blocked anyone accessing us through our webserver. We’ve tried many changes but cannot seem to get past this.
When it locks up, the HP 3000 keeps running but won’t accept any new sessions. Which means our clients can’t run searches. Which is very bad for us. Sometimes we can stopnet and startnet and it will work for a while, but then the errors start again. Eventually, we have to coolstart to be able to have clients log in.

Simulator for Classic 3000 gets third release
A third release of an HP 3000 Series III simulator is now available from the Computer History Simulation Project website. J. David Bryan of the project reports the software which simulates the old MPE V HP 3000 Series III now has a cold dump facility.
Entering the DUMP command simulates pressing the ENABLE and DUMP front panel buttons. The contents of main memory are written to an attached magnetic tape in a format suitable for analyzing with the DPAN4 program provided with MPE. The new SET CPU DUMPDEV and SET CPU DUMPCTL options specify the default device number and control byte for the dump.
Known as the SIMH project, the software is aimed at hobbyists who are using MPE V programs and utilities. Even though a power failure is not a desired event, the simulator has a capability of creating one. This is in addition to yanking the plug out of the laptop or PC running the simulator software.

Power outage, or no problems? It's been quiet on the 3000-L. "Yeah, too quiet."
In the classic war movies, or a good western with Indian battles, there's the moment when someone notices the silence on the field. "It's quiet out there, Sarge," says the more innocent hero. "Yeah, too quiet," the non-com replies. That kind of quiet might be the sound we're hearing from the 3000-L mailing list today.
It's been five weeks without a new message on the mailing list and newsgroup devoted to MPE and its servers. Advice and solutions has flowed for two decades and more off a mailing list that still has 498 members subscribed. The number of subscribers has remained steady over the last three years. Like the number of migrations in the market, the exit from the list has slowed to a trickle. So has new traffic, of late.
The silence may not be ominous. In 2016 the 3000-L is used almost exclusively to resolve MPE/iX problems. The hardware posts are limited to the rare announcement of used server prices, messages that the members still howl at if they don't include <PLUG> in the subject. The server hasn't been sold by HP in more than a decade, but its owners still don't like to be bugged by sales messages. They solve problems in a grassroots manner. As a notable ballplayer once said, you can look it up. There might be no problems to solve.
However, no messages at all over 35 days sets a new record for the 3000-L quiet. This 3000 resource was much more lively a decade ago. And 20 years back? Well, HP was still selling enough 3000s in the fall of 1996 to be sending its new marketing manager Kathy Fitzgerald to speak at an Indiana RUG meeting about the new servers. There was also advice on storage compression, because compression-enabled DDS drives were becoming more common.
Good advice: If you can find a DDS tape drive from 1996, you should take it out of service. Your MPE server, no. And evergreen advice from the L is still available online. Jeff Kell, the deceased 3000 guru who started the server on a University of Tennessee at Chattanooga server, built it to last.

Re-SUSAN services: off-label, or standard
As the 3000 servers age, their components are failing. It may not be a common event yet, but when it happens, getting an HPSUSAN number transferred to new iron has some options. One of the alternatives is a mighty fan to forestall the re-SUSAN processes.
Pivital Solutions' Steve Suraci reports that HP's still servicing 3000 owners who need an older HPSUSAN moved to replacement hardware after a failure. "In our area HP still provides the service to officially update the SUSAN. That's how we'd deal with it, but I'm sure other providers would differ."
When a 3000 manager has no provider anymore, they're likely to look for an off-label solution. In the drug industry, off-label is a use of a drug for which it was not intended. HP never intended to give independent companies the ability to change an HPSUSAN. That's why its tools were protected with a lockword. Then again, HP intended to move MPE/iX to Itanium, and to serve 3000 owners with no end date for support. Everybody knows about intentions can turn out.
Enter Immediate Recovery Solutions. The Bay Area company's history is using software that gives one key HP support capability to owners of 3000s. The Immediate in the company's name refers to intent: To get a 3000 back online, if HPSUSAN is standing in your way, as soon as they can get access to your console,
If that seems rather intimate for a first encounter—saying here's my console on the Internet, and now do your best — then the value of a relationship with an ongoing support provider becomes plain to you. So on the first day a 3000 needs to be replaced, but keep its original HPSUSAN to preserve booting up old vendor software, the choices are three. Call your support company for standard service. Call Immediate Recovery and go all the way on your first date. Or look around for a hefty fan, if you're lucky.

Dancing the Samba services tune, MPE/iX-style
Ten years ago this week we were promoting instructions on how to use Samba better on HP 3000s. Samba is "a group of programs that allows a Unix host to act as a fileserver for Windows platforms," according the MPE/iX documentation rolled out in 1999. The file-sharing and printer sharing software which has been a part of MPE/iX since the 6.0 release "allows Unix-like machines to be integrated into a Windows network without installing any additional software on the Windows machines. Many different platforms run Samba successfully; and there are nearly 40 different operating systems which support Samba." And many more now, a decade later.
HP brought features of Samba to the 3000 in a port called Samba/iX. "It is a solution for those wishing to access HP 3000 disk storage and printers (both networked and spooled from MPE/iX) from common PC client operating systems like Windows." Samba/iX allows access to disk and printer resources of MPE/iX by providing standard SMB file and printer services that are accessible from PC clients and their applications. An administration tool called SWAT makes Samba so much easier to use.
Samba 3.0.22 is distributed by the following MPE/iX base patches. Your independent support provider should be able to help you round one of these up. They've got the latest functionality.
- SMBMXY6D (BT) for MPE/iX 6.5
- SMBMXY6E (BT) for MPE/iX 7.0
- SMBMXY6F (BT) for MPE/iX 7.5
The (BT) stands for Beta Test. HP never cut the 3.0.22 version loose as a general release (GR) version. For reference, the following are GR versions with less functionality.
- SMBMXG3A (GR) for MPE/iX 6.5
- SMBMXG3B (GR) for MPE/iX 7.0
- SMBMXG3C (GR) for MPE/iX 7.5
Even a total 3000 network newbie can get Samba up and running. Samba must be running before you can run SWAT. Here's some useful info when getting SWAT going.
In SERVICES.NET you'll want a line that reads:
swat 901/tcp # Samba/iX Web Admin Tool
In INETDCNF.NET you'll want:
swat stream tcp nowait MANAGER.SYS /usr/local/samba/SWAT swat
(adjust the path to your SWAT NMPRG)
