Keyboard remapping? Sun kb on Win PC.

I have an nice old Sun Micro Systems N-107 keyboard and I would like to use it on my PC. I hooks up via the PS/2 plug and most keys work, it is just that some of the mapping is not correct for Windows.

Before I look into registry modification, Is it possible to remap using autoit? something like the hotkeys.au3 so that the keys that are missed matched can send the correct value?

I am not interested in keylogging or any of that stuff, just a way to use my cool old keyboard.
