][+ lowercase adapter?

[Steven Hirsch <snhirsch@gmail.com>]

I picked up a ][+ with a small board on the pins between the keyboard and the 
encoder board.  It says "HUME" or "HOME" in a stylized logo.  There's a wire 
soldered to the Apple encoder and another to pin 1 of an LS251 in the right 
rear corner of the board - just in front of the joystick socket.  There's also 
a Bourns trimpot on the board with no marking for function.

I don't seem to get lowercase letters, but may not be understanding how this 
is supposed to work.  I was a latecomer to the A2 world in that my first 
machine was a 2e in 1983.  Missed all the fun with ][ and ][+ :-)

Also, what does the slide switch on the keyboard encoder do?
