Why not?  The technical reference manuals for the various Apple IIs always
list three memory addresses for softswitches:  set, reset, and read (where
the status of the switch is in the high bit).  I'm on campus right now, 
though, so I can't look up the addresses, but I'll do that when I get home
and post them here.  (No, going home won't mean a long time from now. :-) )
