Cougar sinks its sharp claws into the mechanical keyboard market
From the earliest PC days, keyboard had processors, even if most people weren't aware of them. They couldn't be used for much else other than polling the keys, but they were true microprocessors.
I mention this because the Cougar 700K has a processor in it that would probably see off all the 8-bit computers I owned and possibly most of the 16-bit ones too.
