This week, meet a reader we'll Regomize as "Dennis", who in the early 2000s worked for an outfit that had decided it was so good at tech support it might as well rent its people out to others, too.
Dennis's main role was in-house support, but one day the phone rang and he was summoned to one of his employer's external clients – the local Chamber of Commerce, an organization he recalls as largely staffed by a jolly middle-aged workforce.
[1]
"They were the friendliest bunch of people I'd ever had the pleasure of supporting – always offering a cup of tea and a biscuit when you went to see them, and never complaining about their computers," Dennis recalled.
[2]
[3]
The call summoning him to assist came from someone uncharacteristically flustered, a fair enough emotional state given the request opened with: "There's smoke and a burning smell coming from my computer!"
Dennis literally ran the mile to the client's office because his employer didn't have a car spare and the client didn't have parking!

After a mile of exertion, and further huffing and puffing to get past reception, Dennis could not help but follow his nose to a small cloud of smoke dissipating smoke over a workstation.
A question or two yielded a theory about the cause of the flameout: the user had been trying to plug in a USB scanner.
[8]
But the user – as so many have done before and since – had the USB-A plug the wrong way up and therefore struggled to connect the scanner.
Nevertheless, he persisted. And even managed to get the cable all the way into the port.
At which point 5V shot up the wrong wire, the ribbon cable between the USB port and the motherboard fried, and the smoke started pouring out. Thankfully the damage was limited to the ribbon cable so Dennis was able to fix things up quite quickly.
[9]
But as he did so, he noticed something else: the user's PC ran an early release of Windows 95 that did not support USB.

Re: Can't put my finger on it
There is normally red text at the top of the article that says 'ON-CALL' that is missing.
Re: Can't put my finger on it
The "something missing" is - "...for that is not his name..."
How on earth did the editors let that omission through? Heads should roll!
Re: Can't put my finger on it
It looks like this one was done in a bit of a hurry.
Re: Can't put my finger on it
I noticed that part was missing right off, I chalked it up to part of the El Reg redesign, first remove Paris, then Dabbsy (https://autosaveisforwimps.substack.com/ )... then the banner for the category. What's next, removing the Vulture??
However I was referring to the story, too short, not enough action, other than running to the client.
25-pin D-type RS232 plug rammed upside down in a socket. Socket survived, culprit made to replace 25-pin plug (most of the pins wired!)
Cup of tea... how about glass of very agreeable sherry at 9am (on the premises of a wine merchant)
Used to train students using "AIM 65" development boards - 6502 with all I/O on 4mm breakout to a side panel. The kids blew the 6522 i/o ports up all the time so, exasperated, we decided to investigate how. Those boards had +/-5V in all directions, 12V from an RS232 and even +/- 12V from external PSUs - everything that was available to students in the lab - shoved up every external orifice and we could not just blow the 6522 i/o ports ... We gave up, accepted that the kids were better at destruction than we were and bought another load of 6522s.
One word.
Static.
Re: One word.
tried that as well ... could never just blow single 6522 i/o ports
When I was doing electronic systems in college - certainly with a few people that shouldn't have been allowed near anything electrical, we had one guy who produced entertainment.
They used to have these plug boards with which you could fit components that was sort of a bit like lego, you could slot in these blocks that had components and a description of what it was on it, they were powered by a separate 12v power supply.
We heard a big bang and everyone turned round to see a mushroom cloud billow up to and across the ceiling and a look of horror on the guys face.
We never worked out how he managed to cause a transistor (I think it was) to lose its magic blue smoke.
We did jokingly create the "Theory of Random Connections" off of the back of what he done which was the running joke for the rest of the college year.
Fun times.
Upside down 3.5" floppies
I have expressed my love of USB-C as it works either way now my eyesight is failing. I was not aware that pushing hard enough would cure that problem, if only to cause a greater problem. The W95 is just the cherry on the cake but raises further questions - who installed W95 on a new PC and why?
I don't think I've even walked a mile at work never mind run, maybe around corridors with some paper in my hand avoiding work. I've cycled to work on 24 hour callout, breathless and sweaty implies dedication.
"You've put the disk in upside down. I'm going to have to take it back to my lab to fix it." Saved a week of stupid fault calls.
Re: Upside down 3.5" floppies
A company I worked for was installing Win95 on "new" machines well into the 2000s. The owner was a cheapskate and had a lot of spare Win95 licences.
Re: Upside down 3.5" floppies
I know of a major company which ran the entire factory production on Win3.1 for a *long* time. The argument was that worked, worked very well and was very reliable. Any upgrade would mean new hardware, OS and production software to integrate with an existing system which might work ... might even work well ... and would provide no obvious benefit (at the time) to production or user experience in return for a massive financial outlay and huge amounts of work ... The upgrade to WinXP was not happening and I couldn't really argue with that one.
Re: Upside down 3.5" floppies
Just a variation of "If it ain't broke, don't fix it!"
Re: Upside down 3.5" floppies
To be fair to them: They were likely not connected to the outside, a Win3.1 (and even 3.11) system fighting you to connect to anything even remotely modern. I'm too young for having really worked on these systems, I had them on my own PC waay back when Pluto was still a planet.
So I can totally get that. Having to replace a hard disk would have been tricky. Those machines did not like anything larger than... 205MB, I think it was? Could be tricked into accepting it with a special driver (or just limiting the partition to the @amountallowed). We all passed a lot of water since then.
Re: Upside down 3.5" floppies
Back in 2004, I did data entry for DHL after uni classes - sweet gig, 5:30 PM to 8:30 Monday to Friday, paid for my beers. The couriers had handheld scanners for registering what they picked up, these scanners integrated with a single air gapped PC in the depot running a DOS program that transferred the data from all the scanners to a floppy disk, which was then taken to another PC and uploaded to the mainframe. Once the data was uploaded, we could start our job, which was taking these partial records and filling them in from the couriers paper copies.
This DOS PC was elderly AF, the floppy disk was elderly AF (of course it was the same disk each day, erased and re-used), so it was quite common to turn up at 5:30 and do nothing/drink tea/chat for an hour whilst the duty manager swore at the old machine.
Re: Upside down 3.5" floppies
At college, when given a blank 3.5" floppy and a sticky label, one student on finding that the label was larger than the target area, placed the sticker so it partially covered the metal shutter. When inserted into a floppy drive, which offered some resistance, it then broke the drive!
Cue an interruption to the lesson for a brief demonstration on where to place the label.
Re: Upside down 3.5" floppies
I had to think about that for a minute - yes the labels wrapped around the bottom of the disc (when did the name change from diskette?) - Nurse! more dried frog pills please.......
I worked with a colleague who many years ago was fixing a PC and complained that it was not working when powered on. I took a look a litle later and the BIOS chimes were pretty much indicating "no ram". The box had 2 sticks of RAM in them so that is wrong. I took the sticks out and to my surprise, I saw 2 sticks of DDR which were in a slot where there should be DDR2. I was baffled as the notches are wrong, so I compared the chips and the notches were correct. My colleague came back I asked "how did you get these into the motherboard ?" and was told "it took some pressing, but they finally clipped in"
correct RAM and MB worked, RAM into an older bit of kit to test and it worked, so no real damage, just bewilderment on my behalf at how they didn't stop, but just persevered, and this was a colleague with years of experience in the support team - so not a PFY from college
Wrong RAM
Well, he was only following the instructions on the memory stick : RAM.......
Years ago my then boss took it on himself to do a RAM upgrade on a PC. I generally tried to keep him away from such things for good reason!
After some huffing and puffing on his part he switched the machine on, only to be greeted with a nice curl of smoke and a smell of burning. He'd somehow managed to half insert the DIMM the wrong way round, despite the asymmetric slot, and decided that would do.
He probably had 40 years experience in IT, just not with PCs of course.
Reminds me of someone who for
He inserted an SD card into his new digital camera - this was back in the early noughties. It didn't want to go in. So instead of turning it round and trying again he used welly. It broke the socket and he had to pay to get it repaired.
It's all of a piece. Given that users will use way more force than you'd imagine necessary, why are we still designing connectors that only work one way round? If it were me, I'd design a card with contacts on both sides so it wouldn't matter which way round it was inserted.
Oh wait: costs....
Any machine is a smoke machine if you operate it wrongly enough.
Did that with my first 486DX CPU. Pin 1 was not in the right orientation, and it made some pretty lights.
Was not impressed. Lesson learnt the hard way.
Re: Are you sure?
First time building a pc.
Fitting an ATX P1 mobo into an old AT case; not all of the holes and riser lined up of course, so I used lego to insulate.
Finish plugging everything in, or so i thought, and turned it on, happy to see the bios flash up.
Then - ERROR: no FDD detected
Realise I missed the power plug on the FDD, and rush to plug it in, forgetting to power off first. Managed to misalign the holes and start to slide it in one pin over where it should have been (somehow the slots and notches didn't prevent this). BZZT-CRACK! Flash! PC power dies. Strange whine.
In shame, turn off, unplug. Align and insert correctly. Expecting nothing, I turned it back on. Whirr, Beep! All is fine!
That's when I learned this PSU had a circuit breaker instead of a fuse (or worse, soldered in fuse; blew a few of those with the 115v switch in the wrong place in my time).
Lesson learned; Measure twice, cut once. And they don't make 'em like they used to.
Supporting the Unsupportable?
Only about 80% of the users I've had to support over my career ...
Re: Supporting the Unsupportable?
When I was younger I thought I could change the world. Now that I've been teaching on and off for about 40 years, I've come to the realization that probably nine out of ten humans are ineducable beyond "eat here, sleep there, bathe occasionally & don't poop in the living room".
Re: Supporting the Unsupportable?
About right. No point trying to push water uphill...
I remember back in the days when I worked in the local IT department at a hospital. The ambulance crew bought a, back then, new and modern digital camera to take pictures of car accidents and other situations for whatever reason. Looking for an easy way to transfer the files to the computer, the bright star and IT master (in his own eyes at least) amongst them wanted to upgrade one of the computers to Windows 2000 so he could get USB support. Back then we were still on Windows 95, so he wanted to take matters in his own hand. I was sent down to talk with them about the matter, and as he explained the situation he slammed a Windows 95 cd down on the desk saying something along the lines of "Look at this, this crappy OS doesn't support USB, that's why we need Windows 2000!". Unfortunatley for him, it was a CD with Windows 95 OSR2, and on the CD itself (or the cover, can't recall for sure) it said 'Windows 95 OSR2 - with USB support'.
I just pointed at the CD and asked him to read out loud what it said.
Outrageous
Support staff running to a job - outrageous behavior. If we don't get a BOFH today it's because Simon read this article and is in shock.
Re: Outrageous
Agreed. Support staff should take thier time to sample the various delights from pubs along the way.
Re: Outrageous
That kind of behaviour just leads to unrealistic expectations.
Can't put my finger on it
I read the article twice now, and feel like there is something missing? Maybe a second cuppa will help me put my finger on it.
