I need circuit diagram of keyboard and mouse port, USB port, DDR port, IDE
port,... for intense study. Would you please point me there with URL?


TIA

All of those are readily available at:

Not all off them, but a good place to start:

nothing there, no those that I need for study in the field of computer
repair services.


the teacher's circuit diagrams are too simple.


google no good for searching.

It's highly unlikely you would have any need for the details in service
work. Almost all repairs are done on the module level - this one's bad
because it doesn't work and another we tried does - so charge the
customer for a replacement.

If you were to use the pin assignments to even measure the DC voltage
on say the ps/2 keyboard port, you would be going further than is
standard 99.9% of the time.

Actually troubleshooting failed modules and fixing them by finding and
replacing failed components is rarely commercially viable - it's
something hobbyists do, not usually trade professionals. The exception
of course would be quality engineers working for the manufacturer, but
they are looking for patterns of failure, not trying to fix individual
problems.

Of course if you want to see them out of curiousity, that's legitimate.


But the diagrams of the ports aren't interesting, because they are just
connectors and wire.

Of those you mention, it's very hard to do anything directly with the
USB or DDR other than hook them up to the intended interface chips.
for the keyboard and mouse (non usb) and IDE on the other hand, it is
possible to make your own devices from general purpose parts, or use
those peripherals in your own project rather than with a computer. Try
your google search with the name of the port and "interfacing".

Yeah, it's a lot easier to have a team of strangers do your
homework for you.

You don't like google? Try msn.
