Won't work with old PS-2 kybd Interface.

Folks,

I had an idea that the Duck might work with old computers, especially those used for Point of Sale systems which still use PS-2 keyboard connectors.

I dug up several old PS-2 to USB converters and tried them, but no joy.  The PS-2 keyboard communications scheme is different than the USB method.

It may be possible to write drivers to make the conversion.

Do the adapters work with regular keyboards?

Apparently some keyboards have a circuit to switch to the older format when they detect the right signal. 

I suspect newer keyboards will, or have, left this out since the technology is dying fast.

A bit of googling showed that it seems to be a clock signal that old keyboards don't bother with. Not sure if this clock signal is sent, or how practical it would be to add it to the firmware(s).
