Bought this recently. It comes with a cable for that wide connector. But I don't have anything to connect the keyboard to. Connecting the keyboard to a computer through the PS/2 connector and the keyboard "boots" up, some LEDs come on and I can toggle between the WS LEDs on the right, but the keyboard doesn't act as a functional keyboard, capslock and scroll lock LEDs can't be toggled (computer was rebooted as PS/2 isn't plug and play). I don't have a male USB to male USB cable to try with. Anyone knows if this keyboard could be a standalone keyboard by itself? I haven't been able to find any manual for this keyboard on the web.
The keycaps are very nice though after a dental tablet bath. There a quite a few interesting keycaps, I especially like the Power icon keycap and the "PROPS" keycap.
