Sun Keyboard on a PC

Hi there! I just received a gift from my friend--a Sun keyboard and mouse. I really like the layout/feel of the keyboard and want to you it with my computers (using a KVM switch actually). Upon researching the keyboard (it's a type 6 with a Crossbow mouse), I found that the connector is called an 8 pin mini-DIN. It looks like a PS/2 connector. That is my problem--I have no computers that use the connector on this keyboard. I tried looking for adapters but have yet to find one. As I said, I'd really like to use it and was wondering how to connect it to my PS/2 KVM switch. FYI: the keyboard was bought brand new on eBay fo $50 USD and non-returnable. I am willing to pay for an adapter to get this to work. Thanks so much for any help! --Sir Hackalot
