The world would certainly be a different place if the Beatles had
been taken from us at that time.

Damned shame that some stupid brit ambulance jock let Jimi drown in
his puke too. The world would be a different place if Jimi were still
around as well.

Today... thank god for wireless hooks on stage.
A fucking brit, It figures.

She probably was murdered then, and what person would take NINE
sleeping pills, so she probably was complicit in his death as well.

Stop talking about this shit in my electronics group.

You may be thinking of Jim Morrison.

JIMI was still breathing when he was placed in the ambulance, and
regurgitated IN the ambulance, and drowned on it IN the ambulance.

That is the NEWS I remember hearing.
You were what? 3 years old?

Hey, I know a guy who saw him lying in the gutter drunk the previous night.

How large ?

I remember one from a Motorola SMPS that was one of the start up resistors
(IIRC 10 - 20 K ohm, about 5W rating, about 1.25" long by 0.3", ~165 VDC max
across it.

This seems to be a common failure in some SMPS.

I've also saw it happen to the small (1/4W through hole) current limit
resistors going to optocouplers on the mains side, used for zero crossing
detection. It's bad enough with some older brand name servo amps, that I
stock spare resistors for them! I only had to refurb one amp so far, but it
lost something like 5 resistors before it quit. The one that stopped it was
for the regen resistance (to pull the power supply down to reasonable levels
from the energy dumped into it from regen), which is only used for short
periods of time, but potentially repeatedly (pick and place machine)
Electro-migration presumably.

Possible. I presume from the very localized damage that one it started, the
voltage potential / power in that area increased, driving the failure mode
faster, thus increasing the voltage differential and localized power in a
runaway fashion. Towards the end, it may have been more of an evaporation
process.

It actually looked like the resistive material corroded away in the small
area leaving little stains on the ceramic form..

Even Nichcon caps leak - I had to recap something like 127 of their 125 deg
C caps after doing a repair (open resistor - mentioned in other post) on a
servo amp and noticing almost all of them leaking in that unit. The caps
give off a characteristic cat pee smell. The other 4 or 5 amps had the same
caps leaking. The servo amp was approaching 10 years old at the time. About
6000 hours of use later, the amps are still working fine and will be soon be
decommissioned with the machine.

I have owned (still do) several ATI AIW cards of several different
busses, and have NEVER had a MOBO that they wouldn't run in.

The only problem is that ATI are snobs about providing fucking
drivers. So I quit buying their CRAP, because without comprehensive
driver coverage (Linux), the best piece of hardware is nothing more
than a total piece of shit when it comes to PCs.
Perhaps the problem was that the MBs were by Intel?
Then again, i gave up after trying 5 other video boards in the MBs.
AGP 2.0, 3.0, 4.0, "universal" cards (like the AIW) all failed to
work on the chosen Intel board.
ATI fails to tell us if their damn "universal" AGP 2x/4x board really
works with both specs; i bet only with 2.0 .
On pre-AGP8.0 stuff, it is a wonder that any (randomly chosen) video
board worked with any (randomly chosen) MB!
Motherboards that are supposed to support multiple flavors of AGP,
video boards that are supposedly "universal" and insufficent eXplicit
(yes, X-rated) information to determine if a given combo *really* works.
AGP 4.0 boards that are really 2.0 does not help; back still further
in time, i understand there were at least three flavors of AGP 1.0!

Sems the onlyway to beat that BS is to get everything AGP 8.0 before
16.0 appears, or dump AGP crap and go PCIE or whatever the newest video
connector/spec is.
Just wait; someone will figure out a way to have variants on that and
screw the public again.

There will never be an "AGP 16.0

PCIe and SLI are the new kid on the block, and no MOBO makers will
be looking back, and very few still make an AGP board for slow
upgraders.

My AIW AGP 4 worked in both 4 and 2 MOBOS, but I buy ASUS MOBOS, and
have never had a problem with them.

He's an idiot. He also claims to be "tapping into my many open
ports".

Methinks he likes men.

You think of your asshole as an "open port"?

Maybe because ASUS knows what they are doing?

Another interesting failure I sometimes see is resistors with a large
voltage differential going open! Sometimes the resistor is dissipating
several watts, other times it's dissipating several uW. Removing the
resistors coating shows that the resistive material had disappeared in a
small area!

In the case of true high voltage circuits, this is common; it's
corrosion.
Not the usual salt-water sort, but St. Elmo's fire is also an
ionic environment, and chemical attack is not picky about
the difference.

The screen adjust resistors on old TVs and video monitors are
notorious for failing in this way. Easy fault to diagnose and
track down, too!
