I burned a floppy drive

Logic signals typically don't drive much of anything except logic
inputs. It's a well-known fact.
There is absolutely nothing to the term "data line" that suggests
an open collector output and to suggest otherwise is simply wrong.

Open collector or not, low current (given the context) is common.
Which was made clear and fully explained in what you sniped. In
particular "In the case of a floppy, however, the outputs are open
collector pull downs."

Which makes your post look like a pointless troll.
But then, if you hadn't snipped that out it would have been even
more obvious you're just trying to be an ass.

And you a tough guy wannabe.
Yes, they are and no one suggested otherwise. But if you're trying
to imply
that blowing an output can't result in a failure that causes a
chip to
pull excessive current and burn a trace, or cable wire, then you
are sadly mistaken.

original posters problem.

Nice try at changing the terminology to cover your ass.

Check up on "data line" containing busses and you'll discover they aren't
all open collector.

Open collector or not,

Which was the point here: That "data lines" does not mean "open collector."

"Low current' when operating properly doesn't necessarily mean 'low
current' when busted.

Which makes your post look like a pointless troll.

No, it simply proves that yours was, or else you wouldn't have had to snip
in order to try and make yours sound rational.

And you a tough guy wannabe.

It had to do with the message I replied to. And if you can't follow it then
stop making an ass of yourself.

LOL. Well, at least you admitted it.
 
Well, that's partly true but incomplete as a 'data line' could be a driven
output as well. And, in that case, while "ZERO VOLTS" is valid it could
blow the output if the circuit is trying to drive it to a 1 state at the
same time.

Do you know, in 14 years of building PCs I've experienced that a sum
total of ZERO times? And it'd still not make a floppy cable glow...
 
No I'm not. Apparently I am wrong about this yet I can't explain why
there was smoke and sparks when the floppy was hooked up.
Click to expand...
Quite simple. Dead short between +5/+12V and ground on the power side.

You've never experienced a "data line" that is actively driven?

Boy, you must not have looked very hard.

you mis connected the power cable (always thought that those connectors were an
abortion)................psu should have shut down after the short showed itself....
Click to expand...

That would explain the fire, but aren't the power connectors always
polarized? I don't see how they can be plugged in backwards, if that's
what you're saying.

I somehow missed this thread before, but I managed to burn up an IDE pc
board (the one on the bottom of the drive) several years ago by somehow
getting the power plug reversed. As soon as I turned the computer, it
went "poof!" Fortunately I had another drive exactly like it and was
able to recover the data by swapping the pc board.
 
John said:
Maybe you deserve some hostility when you give bad advice about an
issue which involves critical hardware failure.
Click to expand...

I don't think you can find any "advice" in my post. Since several
people were good enough to corrected me blandly, I doubt that anybody
suffered much from my post. It seems that the world is still spinning.
Apparently you
freely give advice about important things you don't understand.

I try to avoid it.
 
A tough guy wannabe troll who routinely quotes hundreds of lines of
irrelevant text and then tells others how to post.

Yes, they're polarized but it's a weak connector design and can be plugged
in wrong with little effort. The easiest mistake is laterally off by one
pin and that can cause a dead short. If it's enough to crowbar the PSU then
you're ok but if the PSU can handle the load you get fried wires.

I see you've added new lies.

Do you think that using double quotes instead of single quotes is

If you find a site on English grammar somewhere it will explain to you what
double quotes mean.

No, I've never experienced a floppy drive die because the cable was put

Neither have I. However, it is not because "They're DATA lines," as you
claimed. It is because they are open collector, as I explained.
Boy you must be stupid...

Wrong again.

When you post, the objective is to be understood by other people. I
doubt anyone understands why you quote your own words. Maybe you are
trying to confuse the discussion? Are you asking for help with the
quoted words?

I wasn't quoting my own words. I quoted "data lines" from Conor's post
"They're DATA lines." But, of course, you snipped it because, it seems, you
can't handle an honest discussion.

You're obviously the one confused to hell and back.

I do have trouble with your haywire discussions, your contentious,
mis-informative posts which go in every direction.
