I had one on my ][+. I remember a couple of wires had to be run to the
motherboard. One enabled true Shift key usage. The other I can't remember. If
you don't have a wire running to an IC on the motherboard, that explains why
your Shift key isn't working. It could very well be the same spot where the
"traditional" Shift key mod is made.

003- I got a free IIGS but with no GS ADB keyboard cable!
Where can I get one?
Jack Somers and Supertimer report that ADB cables which will work fine are
available at low prices from stores which carry Mac supplies.
An alternative is to get an SVideo cable from your nearest video/audio
electronics store. Although these cables have no external shield, all four ADB
lines are connected. I tried one on our GS and it worked fine. One thing: the
absence of an external shield may produce extra TV/Radio interference.

004- How can I make a PC-to-Apple Joystick converter?
If you are looking for the best stick at the best price for your Apple II,
building a simple PC-to-Apple2 joystick converter is the way to go. Practically
every computer stuff store carries PC sticks and you will have a wide selection
of brands and models from which to choose.
Note: The converter detailed here will not work with "auto-fire" circuits
included in some PC joysticks. If you use an auto-fire stick with this
converter, "auto-fire" should be switched Off.
For a modified design which supports both auto-fire and non auto-fire operation
see FAQs Resource R030PCA2RF.GIF.
My PC stick is a standard CH Products "FlightStick". A resistance
measurement produced a disconcerting revelation: the X and Y pots top-out around
100k Ohms-- 50k less than a standard Apple II stick! Fortunately, you can
compensate for the difference just fine by adding a bit of capacitance. The
finished converter is shown below:
