   That seems vaguely familiar.  If the software doesn't bother doing a full   
   keyboard decode, then a bad key in the same row or column would be seen   
   as the "break" key and nothing can happen.  I don't know if this is the   
   case here, or even if the "break" key is part of the keyboard matrix,   
   but I'm sure that sort of thing was done at times.  In this case, all   
   they'd want is something to indicate that the user does not want to boot   
   from the floppy drive, so there's no good reason why they'd be pressing   
   some other key than "break".   
      
   I remember one example of this.  When the Color Computer III came out,   
   there was that photo in the ROM that could be displayed with a certain   
   key combination.  Rainbow magazine had a contest to come up with other   
   ways of displaying it, I figured out what was going on and presented   
   a big of code (and won a prize) but most of the other winning entries   
   were about other key combinations.  That wouldn't have worked except   
   that only partial decoding had been done.
