   Hello Michael!   
      
   Okay I get it... so If I were to have my peripheral card listen to the RESET   
   line and immediately check $C000 for the keycode-generating key of choice,   
   then this would cover my scenario of detecting a keypress during startup   
   right? Or is the RESET line    
   by itself not enough to determine ctrl-apple-reset occurred?
