The PS/2 connector also has pins for the PS/2 mouse (I have a schematic for the Y-adapter, though I can buy them locally at Hard Drives Northwest, for $8 or $9.) Whether your computer wires those pins up or not, I can't say The site I got the Y adapter schematic from seems to be down (German site IIRC.) You do need to use the Y adapter (you can't plug the PS/2 mouse into a keyboard connector directly. WHY, I don't know! Dumb IMHO) Oh, and for pretty inexpensive AT to PS/2 adapters, I think C-Gate (http://www.computergate.com) asks 79 cents for those? (I've thought of offering to mail such for the price of items + mailing, next time I do a C-Gate order, but just haven't done it, for those in the EEU etc. Some small parts would mail in a little pouch or cardboard envelope, pretty easily. (Receiver's to handle duty/tax/etc.) Same for some electronics parts, I get past the local electronics stores & the local airport post office regularly, need to go there today in fact - they're open 24/7 almost all year.)
