DC to ps/2, keyboards!

Hi, I have 3 useless dreamcast keyboards doing nothing, and my other pc needs a new keyboard..... Is there a way to convert my dreamcast keyboard to a ps/2 or usb to use on a pc? I assume theres adapters to use DC pads on a PC but they prolly don't support keyboards.... anyone help? :)

You need an adapter, like this one:

But would this support the keyboard also? I have a ps2/n64 one for the pc, and it regs as a 16 button controller only.
