dvorcolI have one of these - a grey ps/2 version which I bought from UKKeycaps a few years back and I love it. If you end up getting one and need any help programming it let me know. There is a system requirement though; you'll need a true 32bit operating system. I was able to get the scancodes for main media functions working which was about as complicated as it got. I'd recommend having a read of this topic over on Deskthority: https://deskthority.net/workshop-f7/programming-access-is-keypads-t8468.html
BobtheSpaceCadetIt just occurred to me I should clarify this point - you'll need a true 32bit operating system to program it, but once it's programmed you can use it on any operating system that will recognise a PS/2 keyboard
