ERROR! ERROR!  The annunciators (AN0, etc) are TTL outputs. You can
run an LED if you use a 7404 to up the current drive, but they are not
inputs.

The Pushbutton inputs are different, of course. And there are only 3,
unless you are sneaky. You can connect your input to a mono mini-audio
plug, and plug it into the cassette input port. Then if you short out
capacitor C11, you have input 4. Although it might be inverted. From
Applesoft that is no problem though.
