At Style Keyboard Question

I have a Pentium133 system that has a bad AT style connector on the motherboard. Is there such a thing as a PCI card that can convert this machine to a PS2 style keyboard?
 
Thanx RickH, but it's the connector on the motherboard that is bad. This computer is in a lab at the local Catholic elementary school and they have very little money, so they are interested in salvaging as much of their stuff as possible. Believe it or not, this Pentium 166 is the third most powerful computer in their lab. Anyone else have any ideas?
 
They used to make a critter called a bus mouse. Connector was similar to PS/2 but it was not the same electrically. Plugged into an ISA card that you could buy separately or get it with the mouse. Haven't seen them in years, however.
 
You might try to get an old junk MB (386,486 etc) and try to remove the keyboard connector. Try it on the junk board first, there are only 5 pins. Good Luck.
 

RickH may well have hit the nail on the head.

The only alternative I can think of is to find an entire motherboard to swap-in.

Actually this might be a better idea than I originally thought.

Geeks can't throw anything away. Maybe someone on AnandTech has an exact replacement board just gathering dust & would be willing to forward it to you.

What kind of computer is it? Homebrew, Dell, Compaq, Gateway, etc, etc. Be sure and specify model if you can.

 
PS/2 and AT keyboard connectors are identical except maybe in their arrangement of the pins. I know this because I'm using an IBM PS/2 keyboard with an AT cord soldered to its circuit board.

Most likely all you have to do is resolder the motherboard's AT connector (solder cracks are usually invisible), but if it's broken inside one of the sockets, just buy another connector (very common). To remove the connector, use a 35-40 watt soldering iron and .08" wide copper desoldering braid. Do not use a solder removal plunger or suction bulb.
