   Drop by the Applesoft Basic reference/FAQ I wrote at
http://www.visi.com/~nathan/a2/faq/asoft.html section 3.3 "Text Input
from the keyboard". I quote:

The final, and most on the metal method, is to read the 1-character
input buffer yourself. If the return value from 'PEEK (49152)' ('PEEK
(-16384)') is identical, but uses one more character) is less than
128, nothing has been hit. If it is greater than 128, the key hit has
ascii value of the return value minus 128. Thus, 'A$=CHR$(PEEK
(49152)-128)' will set A$ to the key that was hit.  'POKE 49168,0'
('POKE -16368,0' is also identical) will tell the system that you've
dealt with the keypress; if this is not done, it'll continually report
that one key down.
