2+ keyboard encoder enhancements

[adrianw@cassius.ee.usyd.edu.au (Adrian Whichello)]

Hi All,

I was going through my 2+ spares (still some available, be quick before the
borers set in) and found that one of my spare keyboard encoder cards actually
had the second switch (not the ctrl-reset switch) and the db-9 pin male
connector soldered onto the board. All later model 2+'s keyboard encoders had
the necessary solder pads and the silk screening showed where the second switch
went, but I'd never actually seen one in place. Does anyone remember what it
was for?
