If you've ever been in a mainframe computer room, one
thing you remember, is how cold it is in there. You will
forget all your delta updates, once you are freezing
your ass off in there.

Operators usually wear suits, like Men In Black. Not sure about (sexy?) female operators. And outside contractors.
I did enter and exit a mainframe computer room when doing industrial placement in
IBM World Trade (Asia) Corp. in Hong Kong. It's not that "freezing your ass off". :)

Thermal practices vary by installation. Some of our mainframes
were installed in building spaces with weird dimensions
(long and slim). Those style of facilities did not use
the "killer" chiller plant. You could dress normally there.

And nobody wore suits in our mainframe facilities. Same goes
for the university mainframe. Attire was casual. You would
wear something heavy enough, for the conditions.

Better wear a full face-mask and a disposable coat. Abattoirs are as dangerous as mortuary in hospitals. The floor is always dirty.

No.
3270 terminal emulation is available since MS-DOS days. You needed a
3270 adapter to do it, and relevant software of course. Nowadays, I
believe IBM mainframes can bridge with TCP/IP and run 3270 terminal emulation on top of it. The same should go to IBM AS/400.

Few Windows 11 or 10 devices are present on mainframe servers(an

Why not place some Windows machines inside a computer room if they can
run terminal emulation? I think operator consoles of IBM mainframes are still 3270????
Enterprise admins are not jumping through hoops to use 3270 emulation.
Which is strange!! There is nothing wrong about 3270, VT-100 and ANSI.
To secure these old protocols, just box or wrap them with a security shield???

Again, missing the rationale. Not necessary to have endpoint devices in
the mainframe room. Nor is there much of a need to waste a body to use
them. That same body can do the same work externally.
Old school.
Already explained the better(performance, time, expense, features) technology for the same task.
SAE/WP3, OWE, 192-bit, digital signed, secure bootstrapping.

Lol..I passed along your 'rather talk to IBM suits' comment on this

- "Barking up the wrong pantlegs'
- "Askhole approach"
- "Try changing the meds"
Your continued quest on mainframes - 3270, having DOS, Windows, Linux is
the essence of novelty..asking for something or about something no one
needs.

fill some void, needed attention, or spark conversation...it really

I have not been hands-on close to IBM mainframes since the OS was called MVT, but I am pretty sure that real 3279's are long gone, except in the incarnation of tn3270 (3270 over telnet). And I suspect the console
complex is a PC "service processor". I wonder if it runs OS/2?

Did you notice that those fish-tank computer chassis usually have no handle to lift them?
What if the glass was so slipper and you dropped the glassy fancy chassis? :)
I can see why manufacturers love glassy computer chassis. And it must be black so that you cannot see them in the dark.
And for those people who are worried about dropping their case,
you can get one with a really crappy handle :-) I expect the
first thing you'd be doing, is plotting how to replace that
with a decent handle.

Can you use sonic sound wave to break tempered glass? I doubt any glassy computer chassis has sufficient damping. :)
Also in terms of security and privacy, a hidden camera on the motherboard (disguised as a component) can watch you all day. Or maybe a really nano-microphone....
I think people have reported that the glass breaks into tiny pieces.
Heat would be easier to apply, followed by a splash of cold water should do it.
The last computer case I bought, there were three options. And I
picked the option where there were no glass panels. That's because I knew you'd be around with your sonic thingy, to test it :-) The metal
case is pretty robust.

glass used in bus shelters and other similar places is safer, because
the tiny pieces are (an approximation to) little cubes, with fairly
blunt points, rather than long jagged pieces with sharp points/edges.

I don't care how things break into safe pieces. Nothing breaks in a
safe home! :)
Do you break your dishes and cups every day? Your job breaks things?
Now that's to home safety like "What could possibly go wrong?" is to engineering.

Have you ever used English-only computer system, with no graphics? Did
you use DOS (PC-DOS, MS-DOS) before? THose are pre-1997 computer stuffs.
Back then, we can do everything in isolated personal computers, without
any need for mobile phones nor internet. NO HTTP, no HTML, no whatever. :)

You've led a much-too-sheltered life, if you haven't
been constantly making things.
I once built a kite, that was 12 feet high and 9 feet wide.
The tail on the kite was 50 feet long.
It took a 30MPH breeze, to get that airborne. The first
day, I couldn't get enough breeze to do it. But the
next day, I didn't have to run with it. I figured this is
great, I'll have no problem getting this up in the sky.
After a harness adjustment, away we went.
Well, what do you notice when a thing is that big ?

You're running out of field... You have to dump the kite.
And just at that moment, the kite decides to become unstable
and it's heading for the ground at warp velocity.
I had to give a "giant pull" on the string at the
last moment (I knew I was in trouble on the trajectory).
The kite cleared a power line (11kV) by only about six inches :-)
It was never my intention to be over the adjacent street--
with the stupid thing. It started out just fine
over the field I was in.
One of the spars broke on impact. The other spar is still
in the basement back home, as a piece of scrap lumber.
That's how we learn things. By building stuff.
I can confidently tell you, not to do that :-)
Scaling a kite is OK, just not that much.
It was just my luck, a windy-enough day happens by,
for the launch. This was spring kite-weather. If the wind
had not been that high, I would have concluded it would
never get off the ground. Well, it got off the ground :-)

No, they don't.
Fyi...your reply was to person in a time zone where traditional banks
no longer offer or have phased out use of or discontinued updating
previous issued 'physical passbooks'
Same for this reply's timezone with the exception of a few and rare regional and local only banks(non-traditional)
I have not seen banks using thermal paper here. Maybe the cash machines
on the wall, but I don't think so.

The self-service machines inside the bank which can scan a bunch of
cheques into your account prints mini copies of them on thermal roll,
along with the OCR'ed values (wrong about 10% of the time)
We don't use cheques here 🙂

We only have bank cheques, guaranteed by the bank. Used for things like purchasing a house.
Australian Banks stopped cheques about 18 months ago. Previously I had
been giving Nieces/Nephew cheques for Christmas. Last year it was EFT or nothing .... well, I guess I could have given bundles of Notes but went
the safe way.
