   Why $0401, $0801, $1c01? Why not $0400,

   Hi all,   
      
   I figure that someone here probably knows why CBM's basic RAM always started   
   at $xx01 addresses, like $0801, $0401, $1001, $1c01 instead of $0800, $0400,   
   $1000, $1c00?   
   What is sitting in that one byte, or what role is it playing?   
   I realize that I've always taken that for granted, but never asked myself why.   
   Or I knew it at some point in the past and forgot.   
      
   Cheers   
   /Philip
