I have a dim memory (these days, they all are) of seeing something in a 
Guitar Center in San Francisco around 1979 -80 called a "Music Mate", which 
was a portable (came with carrying case) practice keyboard -- the kind of 
thing serious piano students would use (hence the touch feature).
How one would go about adding electronics, I have no idea.
