false.

There are no Apple branded electrolytic capacitors, or
Apple factories for PSUs. (It says right on the side
of the PSU in my Mac G4,

that's a 20 year old computer long obsolete, and caps aren't the issue
anyway.


So you admit then, that it happened and it's true.

"20 year old computer" equals "Apple made it and was proud of it
at the time".

Because flickr is so much fun to navigate, here is the picture
as seen in my browser.

Dongguan Samsung Electro-mechanics === This is the OEM making
the subassembly
Made in China
S/N:
Apple P/N: 614-0224 === This is the Apple BOM item

So, yes, yes, Petunia, Apple is not fully vertically integrated.

When it makes sense to buy a subassembly from a third party, they do.

Just as when I worked in my fully vertically integrated company,
if I needed a "ua741", I didn't go down to the fab and hand-hew
the ****ing thing out of raw silicon. I ran down to Radio Shack
and got one for a buck. Lots of stuff came as subassemblies.
When I was in our "computer making" division, the power
supplies were perfectly awful OEM units. "I spit on them"
was the brand name.

What Apple uses for OEM, are better quality than anything
we ever put in a box.

HTH,
Paul


That's the way the industry works. Why reinvent the wheel when someone
else has what you want cheap?


It's almost a push-button industry.

You bring a bag of money, give a list of voltages and
currents, indicate what "certs" you want, device dimensions,
what protection features (OCP,OVP,UVLO,whatever), and
you can have a PSU made for you. (We had a division at
work which could do this for you, too. They were so good,
we sold them off, lock, stock, and barrel, to a power
supply company :-/ The employees, never to be heard of again.)

The PSU in the picture (and a few from that generation),
have some of the same voltages as ATX. The difference is,
that PSU has a +25V DC output for running a computer monitor.
Apple "attempted" lockin, by offering some monitors that
didn't need a power cord. They would get their power from
a 25VDC output on the monitor faceplate. This did not prevent
the usage of regular monitors, so it's not "real lockin",
but you can see what they were up to. Apple stopped doing
that after a while.

I'm familiar with this, only in as much as I modded an
Apple AGP video card for usage in a PC. I seem to remember
four electrical connections needed slight mods (as well
as flashing in a PC ROM image). Why did I mod a card intended
for an Apple ? It's because I only ever got one driver for
the card, and ATI didn't provide any more updates for the
driver. So I said "**** it, I'll get some usage of the card
in my PC". And I gamed on that card for another five years
after the mod. The Mac G4 went back to using the 9000 it
came with (still good, for what it is).

I just found it ironic that someone was using multiple fake nyms to

Although we had pre-booked for two nights, we didn't like Vegas
and moved on after just a one night stop. Death Valley was much
more to our liking! ;-)


Been a while since I have been back to Vegas, but I am familiar
with the Strip and Circus Circus. Used to go there as a kid and
play the games. I got quite good at a car race one -- found a way
to not exactly cheat but play focused on things most did not so I
won more often than not ... but they got rid of it. I am guessing
I am not the only one who found the trick.

Sometimes it's advantageous not the be one of the sheeple! ;-)

Did you go on to learn about 'computing' so that you could earn a
living at what you enjoy doing?

Got into computing sorta by accident. Was getting my degree in
Vegas (UNLV) in psychology. I worked my way through college to get
that degree by working in the computer labs. When I got the job I
had used Apple IIe systems but nothing else.

Was then put in the library lab which had Macs, DOS machines, and
UNIX dummy terminals. I did not know how to turn any of them on...
but I caught on quickly. I am one of the few who can say I started
working with those three OSs literally on the same day, and very
shortly got introduced to MS Word on Macs, Word Perfect on DOS, and
vi on UNIX (along with other software on each).

Six years later I was running a cluster of education computer labs
and teaching computers to at-risk high school students through the
Upward Bound program. Left college and was a substitution teacher
for a year (K-12 and special ed) and then got a job as head of tech
support and the sysop for a communication system that worked with
the Clark County School district (about 200 schools at the time)
and 100 or so United Way Agencies. To do the training I developed a
way to do it on the system we were using (FirstClass, at the time
owned by SoftArc) and developed what is now known as an online
class (as far as I know the term did not exist). I am sure there
were others doing similar things, but I really do not know of any
other large scale online classes that happened before the one I
designed (and helped to teach). That was back in 1993 or so.

Then I moved to Tucson and did tech support for a bit before being
moved up to being a trainer. I am more of a teacher at heart than a
hard core tech person, though clearly I have a focus on tech.

How about you?

You can find out a bit about me he-
https://www.linkedin.com/in/boaterdave/

If you have any questions, just ask!

I'm off to my bed now, though. It's after midnight!

'nite!

See you have an interest in Raspberry Pi systems (Pies?). I do not
have one but know someone who uses a couple for his own home weather
station... do anything interesting with them?


My son, who's probably about your age, gave me a Pi for Christmas a
few years ago. Sadly, it's still brand new in its box, although I did
open up the box to look at it! I wish I'd had such a 'toy' when I was
forever experimenting as a lad! I'm sure I'll think of something
positive to do with it one day. :-)


I am sure I would find use for one if I had one, but not really chomping
at the bit to get one. The weather station controller is pretty cool but
I am happy just checking weather.com.


Yes - me too! ;-)

Still, I like to tinker. I was one of those kids who had a 101 in 1 (or
whatever) electronic kits who figured out I could have my own TV station
and then boost the power (hoping not to blow the thing up) and then walk
up and down the street blocking channel 8 (used to be the main news
channel people watched at least in my area of Vegas). OK, not exactly
the best thing to do but I suppose worse things kids can get into.

I apologise for calling you John.


I am over it.


You are easily pleased. I like you! :-)

more often than not it is correct! If it's not, the person will
invariably correct me and proffer their ACTUAL name without me asking

For men my age in America the name "Michael" works much the same... so

Odd how you would reference a discussion that happened back in 2015 when
you are so "new" here, but hey, here is the video you are clearly
referencing:

https://youtu.be/NPM_WldEBs0

If you have something of value to add to the topic I would love to see
it. Heck, Owl took that "challenge" or "task" or whatever and came up
with a more complex one. I took that on. We had a number of videos back
and forth, but this is where I show one of my solutions:

Odd that you, a new person to the group, would be so interested in such

Thanks! :-) I hope you didn't mind me asking.

Was that *IT* ..... or IT = https://www.acronymfinder.com/IT.html

You seem to have quite a reputation. I've been impressed with all I've
seen so far. Why have you not been dissuaded to correspond with me by
the shady Shadow? Some folk believe the lies and propaganda some spew
forth here on Usenet. How is it that /YOU/ know that I'm telling the
truth when I tell you that I've had no alcohol, none whatsoever, since
21 March 2018? Please explain to the other readers! ;-)

Not a coincidence if you know your electronics well enough.

The UPS stepped output can cause harmonics that the iMac power supply

false. imacs have no issue with stepped sine waves, nor do other macs.

But not in my case. Is it a faulty ps in the iMac? Could be, but the
pure sine wave output is a much better options. Whether you put much
trust in the GeekSquad or not, they did say that some iMacs are affected
by this. So I went up to another store and asked the same question.
Funny that the store won't stock the cheap stepped UPS, but they do
stock the better ones.

you also shouldn't be running anything off a ups for an extended period
of time anyway. it's for brief amounts of time, to safely shut down.


The UPS has about 2 hours of power before I have to shut down the iMac.

that said, i've run several different macs, pcs, upses and many other
devices for 30+ minutes off a cheap ups (stepped sine) without issue.


But not her iMac. It is not fun to have a hanging process. You have
to, in this instance, bring up Activity Monitor and force quit Finder.

because cheap crap isn't good enough.


Which is why I purchased a better UPS. Problem solved.

Indeed. The fact that the wheel has already been invented, does not
mean that all applications for the wheel have been adequately served.
There will always be new applications, and the demand for different
designs and quality levels.


Agree there. A co-worker of mine had purchased a G5 mac, and found that
it needed a new power supply. One set of caps had a couple of volts
over the working voltage, so he ordered some caps that had twice the
working voltage. Seemed to make it more reliable. Sometimes little
things like this get overlooked somehow.

false.

There are no Apple branded electrolytic capacitors, or
Apple factories for PSUs. (It says right on the side
of the PSU in my Mac G4,

that's a 20 year old computer long obsolete, and caps aren't the issue
anyway.

So you admit then, that it happened and it's true.

"20 year old computer"** equals** "Apple made it and was proud of it
at the time".

Because flickr is so much fun to navigate, here is the picture
as seen in my browser.

the subassembly

So, yes, yes, Petunia, Apple is not fully vertically integrated.

When it makes sense to buy a subassembly from a third party, they do.

Just as when I worked in my fully vertically integrated company,
if I needed a "ua741", I didn't go down to the fab and hand-hew
the ****ing thing out of raw silicon. I ran down to Radio Shack
and got one for a buck. Lots of stuff came as subassemblies.
When I was in our "computer making" division, the power
supplies were perfectly awful OEM units. "I spit on them"
was the brand name.

What Apple uses for OEM, are better quality than anything
we ever put in a box.

That's the way the industry works.* Why reinvent the wheel when
someone else has what you want cheap?


It's almost a push-button industry.

You bring a bag of money, give a list of voltages and
currents, indicate what "certs" you want, device dimensions,
what protection features (OCP,OVP,UVLO,whatever), and
you can have a PSU made for you. (We had a division at
work which could do this for you, too. They were so good,
we sold them off, lock, stock, and barrel, to a power
supply company :-/ The employees, never to be heard of again.)

The PSU in the picture (and a few from that generation),
have some of the same voltages as ATX. The difference is,
that PSU has a +25V DC output for running a computer monitor.
Apple "attempted" lockin, by offering some monitors that
didn't need a power cord. They would get their power from
a 25VDC output on the monitor faceplate. This did not prevent
the usage of regular monitors, so it's not "real lockin",
but you can see what they were up to. Apple stopped doing
that after a while.

I'm familiar with this, only in as much as I modded an
Apple AGP video card for usage in a PC. I seem to remember
four electrical connections needed slight mods (as well
as flashing in a PC ROM image). Why did I mod a card intended
for an Apple ? It's because I only ever got one driver for
the card, and ATI didn't provide any more updates for the
driver. So I said "**** it, I'll get some usage of the card
in my PC". And I gamed on that card for another five years
after the mod. The Mac G4 went back to using the 9000 it
came with (still good, for what it is).

Again, you've provided the insight into the industry. No need to spend
a lot of money doing the research, only to find out that it can be done
by someone with experience and expertise at a much lower cost.

Well, you definitely did the research. Wife did have a step wave UPS,
and the iMac started doing some strange things, (like emptying trash
that doesn't empty the trash and hang). Got her a pure sine wave UPS
and those problems disappeared.

unrelated and a coincidence.


Not a coincidence if you know your electronics well enough.

i do, and it is very much a coincidence. stepped sine waves won't cause
the trash not to empty.


The UPS stepped output can cause harmonics that the iMac power supply
can't handle. I put a new UPS pure wave output and the problem went away.


false. imacs have no issue with stepped sine waves, nor do other macs.

But not in my case. Is it a faulty ps in the iMac? Could be, but the
pure sine wave output is a much better options.


pure sine wave is better but it cannot cause the symptoms you describe.

Whether you put much
trust in the GeekSquad or not, they did say that some iMacs are affected
by this.


geeksquad? seriously?

So I went up to another store and asked the same question.
Funny that the store won't stock the cheap stepped UPS, but they do
stock the better ones.


that means nothing.

you also shouldn't be running anything off a ups for an extended period
of time anyway. it's for brief amounts of time, to safely shut down.


The UPS has about 2 hours of power before I have to shut down the iMac.


higher end upses that last that long normally are pure sinewave.

that said, i've run several different macs, pcs, upses and many other
devices for 30+ minutes off a cheap ups (stepped sine) without issue.


But not her iMac. It is not fun to have a hanging process. You have
to, in this instance, bring up Activity Monitor and force quit Finder.
Which, in this case, also mandates a restart.


no it definitely doesn't require a restart, nor is activity monitor
needed to force quit finder.
