Subject: Apple ][ shift mod.

       Here is how to do a shift mod. on your apple II (not //e). A
recent message on info-apple covered some of it.

       You will have to connect a wire from the shift key to pin 4 on
the game port. It's the fourth pin from the front on the left side,
looking at it from the keyboard end. One of my ancient tomes (the
Superscribe II manual) saya to use a 13in. length of #22 wire, and
strip 1/4" from both ends. This is a bit too detailed, but who cares.
Ho
       How you connect the other end depends on your computer. If
your apple is revision 6 or 7, it has an extra circuit board attached
between the keyboard and the motherboard. If it is revsion 5 or below,
it doesn't.

       For 6 or 7, connect the other end to the second pin from the
right on the 50-pin connector. (right under the asterisk key) The
connector is on the right half of the board. This is the shift pin.

       If it's revision 5 or below, you have to remove the case by
unscrewing the screws on the bottom (all 10 screws). Then solder the
wire to tyhe shift pin pon the keyboard encoder. 

       You can now use the shift key by reading the input from
paddle button 2 (this is where you connected the wire). It works: I'm
using it now with Ascii Express and as Videx Videoterm 80 col. card.

       This seems as if it will work better. Does anyone have more
specific details?
