[GreenKeys] USB-teletype adapters (update #2)

[epvgk at limpoc.com]

Hey folks - 

The boards arrived from the factory today, and (big relief) everything works and looks 
good.  I've been finalizing documentation and firmware, and will be ready to start
taking orders and shipping once I get back from a conference this coming Sunday. 

They will be at https://squareup.com/store/epv-greenkeys

At http://heepy.net/index.php/USB-teletype you can find more info, the manual that
will ship with the boards, firmware reprogramming info, and various other stuff.
