Datadesk Smartboard PC5000 cable

I have a Datadesk Smartboard PC5000, which is a fairly nice ergonomic keyboard. I far prefer it to the Microsoft Natural as it's got a good feel and will put up with a large amount of abuse. Unfortunately, I lost the cable for it. Rather then a standard PS/2 or USB connector on the keyboard side, it uses something that looks like an ADB connector, which then gets converted by the cable to (in my case) PS/2.

I could have tried to buy another keyboard or a cable, but that seemed like an overkill. Instead, I grabbed the adb cable off an old mac keyboard sitting around and attached it to a PS/2 cable. A bit of trial and error revealed which pins to connect.

here are the pinouts; colours are as they were on the particular cables I happened to have and may or may not match what you have.
