Hmmm, was that A600HD bought from a shop back then ?? Then the shop owner made some extra money, cause he must have removed the Kick 2.05 which is the lowest Kick the A600 shipped with !!! Also if your A600 is labeled HD, there must have been a 20,30 or 40Meg HD inside ..... The A600 itself came without a HD, but it wasn´t labeled A600HD then !
It wouldn't surprise that this happened as I recall it also happened here in the states as well
Really it's an unscrupulous dealer trying to make some extra money.
It would be like buying a 2000HD model without the HD and/or the SCSI/IDE controller card.
