By the looks of it if QSECOFR is disabled or the password changed you need a DST to reset it.

Resetting OS/400 QSECOFR Password Using DST - Version 5 and Higher

Resetting QSECOFR with an Unattended IPL

This method is used when:
o You can wait a while before you must to use QSECOFR
o You cannot interrupt the machine for an IPL, and no one will be available to operate the system when the system is IPLing


To reset the system password, you should do the following:
1. From the front panel of the machine, put the system into Manual mode.
2. Use the arrow keys to get to function 21, and press the blue Enter button.
3. On the console, a dedicated service tools (DST) sign-on screen is shown. Sign on with the System Service Tools (SST/DST) QSECOFR user ID and password.
4. Select Option 5, Work with DST Environment, from the Use Dedicated Service Tools menu.
5. Select Option 6, Service Tools Security Data.
6. Select Option 1, Reset operating system default password.
7. The Confirm Reset of System Default Password display is shown. Press the Enter key to confirm your request.
8. You receive a confirmation message telling you the operating system password override has been set.
9. Continue pressing F3 (Exit) to return to the Exit Dedicated Service tools.
10. Take the system out of Manual mode.
The system resets the Operating System QSECOFR user profile to the default shipped value when it is next IPLed. The IPL may be a normal (unattended) one. You must have the system scheduled to IPL or have someone (an operator or someone with authority to power down the system) do it. If you do not, you will have to power down the system from the front panel, and start it from there.


Resetting QSECOFR with an Attended IPL

This method is used when:
o You can not wait, and you need to use QSECOFR now.
o You are available and ready to IPL the system now.


To reset QSECOFR with an attended IPL, you should do the following:
1. With the keylock switch in the Manual position, start an attended Initial Program Load (IPL).
2. When the system displays the IPL or the Install the System menu, select Option 3, Use dedicated Service Tools.
3. On the Dedicated Service Tools (DST) sign-on display, sign on with the System Service Tools (SST/DST) QSECOFR user ID and password.
4. Select Option 5, Work with DST Environment, from the Use Dedicated Service Tools (DST) menu.
5. Select Option 6, Service Tools Security Data.
6. Select Option 1, Reset operating system default password.
7. The Confirm Reset of System Default Password display is shown. Press the Enter key to confirm your request.
8. You receive a confirmation message telling you the operating system password override has been set.
9. Continue pressing F3 (Exit) to return to the Exit Dedicated Service Tools menu.
10. Select Option 1, Exit Dedicated Service Tools.
11. The IPL or Install the System menu is shown. Select Option 1, Perform an IPL.
12. The system continues with a manual IPL. The procedure for performing a manual IPL is described in the System Operation manual.
13. When the IPL has completed, return the system to the Normal mode.


For Both Methods

After the password has been reset, change the password. On the operating system command line, type the following:

Caution: Do not leave the QSECOFR password set to the default. This poses a security exposure. This is the value shipped with every system and is commonly known.

CHGUSRPRF QSECOFR

Press the F4 key to prompt the command. Type a new password, and change the status of the profile to *ENABLED if it is set to *DISABLED. Press the Enter key to have the changes take effect.


Also, an IPL (Initial Program Load is the IBM nerd's slang for "boot" ;) ) normally takes eons because they are not designed to be power cycled often. You IPL'd and the machine remains up for months or even years.

I pulled all the digital guts out of a Guitar Hero drum set and replaced it with an Arduino Pro Mini microcontroller.
Now the $10 second hand drum set is a MIDI enabled drum instrument.

There's a video on how to do this, by the way. ;)

Yeah you can craylink two machines together if you want the machines locally but for network render nodes it's totally possible.

Personally I'd love it if Office depot or even your chain office supply store sold Instapak bags .

They're amazing for shipping weirdly shaped items, especially things like monitors or fragile machines like the O2 or compact macs. Yet it seems the only way to buy them is in packs of 20 for over $250. They aren't financially viable to buy unless you are shipping a lot of stuff.

When I sifted through what remains of Akihabara I did not find a lot of older computers. There was some MSX things but I saw more NEC PC-98 stuff than anything.

One that struck me last night while working at the 3D printer.

What are the odds we can build Slic3r? The web front-end on the makerspace printer is just primitive enough I could actually model and export the work to the printer from the SGI exclusively.

Wrote on the subject of Acquired a PS/2 Model 60 with Reply Corp PowerBoard planar replacement at March 7, 2017, 4:47 p.m...
Alas, you are correct in that you need a special floppy. All of the Microchannel machines needed what was called the Reference Diskette to self-configure when the battery was changed or you added/removed boards. The diskette is different for every planar but MCA machines are well documented so if you can't find it on MCAmafia then you will find it on one of the other MCA oriented sites.
Personally I've never tried subbing in a regular PC floppy drive so I do not have the pinout for the adapter harness (because IBM's PS/2 34 pin floppy interface is NOT THE SAME AS THE USUAL 34 PIN FLOPPY PINOUT) but others successfully have.

Edited: I quickly looked up the Powerboard 60/65/80 and came across this page which seems to have the reference diskette image.

I'm admitting I did something slightly dumb because I thought it would be cool and for my local Makerspace I've been advocating replacing the existing outdoor lights in the parking lot with mid-century fluorescent lamps. On paper it sounded great and I secured two lamps for a test install. They needed new ballasts but otherwise they are fine.

My problem is that I grossly underestimated how big they are. Each lamp is almost five feet long and weighs about 60 pounds. Now that we got 'em there's doubt floating around that they are too big for what we need, plus everyone's optimistic that four lag bolts are all you need to secure it to the wall. :?

The old HP RP5700 that ran my chipping station died. Had to rummage around for another box that had a physical parallel and serial port.
While I was reinstalling I also added support for reading and writing to RFID.

Wrote on the subject of OpenGenera VLM at April 30, 2017, 4:49 p.m...
This is something more out of idle curiosity. It seems originally it was only for Tru64 however someone rather recently ported it to Linux. The documentation to do so is available here .

Without sitting in front of a 64-bit machine myself (I only have the O2 up at the moment) it seems all you need is the VLM, curl (neko_curl?) and that's it however I have no idea if big-endianess will cause issues. OpenGenera would for me at least be a lot easier to handle than running it on some random Alpha box, moreso for someone who runs an SGI somewhere full-time but also wants a Symbolics machine running as a network device without all the hassle of trying to get an actual machine running reliably.

Keeping the creativity ball rolling.

So today while working on the backlights of a 32" LCD panel I looked at one of the broken tubes and wondered if I could melt the jagged end with my butane torch. I could. I made a straw once I fed a pipe cleaner through it.
Then I wondered if I could shape tubes that were not already broken. The big issue I assumed was that the vacuum would try and collapse the tube if I got it too hot. I took a bundle of bad tubes home and tried over a propane plumbing torch, then gave it 12000 volts.

Cool, I could make little neon signs.

Oil burning furnaces have a nice transformer that sits on top and generates a few thousand volts for the arc gap.
