:%s/^.........................//

  [Note: I would probably type the above line into the edit buffer using
   i:%s/<ESC>25A.<ESC>A//<ESC> instead of counting the .'s, then delete
   to a named register and execute with
   "add@a   
   Besides saving the counting, this method lets you undo the change,
   yank back the command and modify it if it turns out to be wrong.]

:%s/info-mac.*00/00/
