Default Replacing a 6-DIN PS/2 Mouse plug

Where can someone buy a replacement 6-DIN PS/2 Mouse plug? The one on
this computer is apparently worn badly. The plug falls out often and
many times when it is plugged in, I have to jiggle it to make contact.
It's not the mouse, I have tried others. I dont think it should be
too bad to solder in a new plug (I hope). On the other hand, I
suppose I could get a serial or USB mouse....

Cheaper and easier to buy a new mouse.
Also last longer.
USB mice, while they usually work OK for most things, sometimes have
troubles if you boot up in "Safe Mode" or other things that haven't
loaded full USB drivers.

The problem when connector shopping, is the connector terminology
has virtually nothing to do with the connector. Which means when
you type PS/2 in a search engine, you aren't likely to find what
you want. With connectors there could be hundreds of "nearly
correct" solutions. And the format of the housing that was popular
seven years ago, might not be popular, or in production today. In
other words, the hole where you plug stuff might be correct, but
everything else could be wrong.

This is an example of a stack for keyboard and mouse. This is a datasheet
and I didn't find someone selling it. This is suitable for modern
motherboards (exceptions are beginning to appear, as some P35 motherboards
no longer have the dual stack).

http://www.powerandsignal.com/docs/P...ht%2012_12.pdf

Tycoelectronics or Molex, are a couple other places to look. This
is a sample Tyco page, for a single connector.

http://catalog.tycoelectronics.com/T...&I=13#features

The picture is deceiving, and the following drawing may be more accurate. I
had to split this URL in two, to get it to fit.

http://ecommas.tycoelectronics.com/c...ction=showdoc&
DocId=Customer+Drawing%7F749231%7FL%7Fpdf%7FEnglis h%7FENG_CD_749231_L.pdf

The 749231-1 is the bottom one on this page, at $1.94. There are none
in stock, so ordering would be a waste of time at Mouser.

http://www.mouser.com/search/refine.aspx?Ntt=749231-1

If you go to www.digikey.com and enter "749231-1", they have 1307 in stock.
Price is $2.91 for a single unit. This picture is a closeup view, so you
can compare it to your current one.

http://rocky.digikey.com/WebLib/Amp/...s/749231-1.jpg

It helps to have the current connector in front of you, when using the
Tycoelectronics site, to find alternatives, or when you go to a shopping
site and try and buy one. My guessing at your needs, is only going to
give you the wrong connector. So treat what you've seen so far, as
providing some terminology, and that is the only value of the above.

In engineering, as a newbie designer, you soon learn what a sinkhole
connectors are. You could produce the most elaborate electronic design,
then get a call from the factory that "the connectors don't fit". To
reduce the risk of that happening, while you can spend hours looking
at those stupid drawings, it pays to have sample connectors in your
hand. That way, fewer bad things happen to you. Some connector companies
have a small quantity sample or order system, so you can get samples.

Sounds like the problem is with the receptacle on the motherboard.

That's what I was saying. The mouse is fine. The plug is worn.
