Here's what set me off on this merry errand: 
http://www.schatenseite.de/dulcimer.html.  This uses an ATmega and little 
else to replace the controller board of a Model M keyboard, making it 
natively USB.  What I want is a downstream port or two to connect a mouse 
as is common with Mac and Sun keyboards.  I have a Sun Type7 keyboard, 
but I can't give up my Model M.
