Actually, no: it came from tape controllers with 16-bit count registers, which were still relatively common not long ago. (The Xylogics 472 that a lot of Sun 3s shipped with has a 16-bit count, for example.) Agreed that it is silly to impose such limits on hardware that doesn't need them, like properly-implemented SCSI controllers.
