IBM's 360 series numbers bits from 0 to 31, with bit 0 being most significant. I know I've seen material where a CPU numbered bits from 1 to 32, with 1 being most significant, but I can't remember the manufacturer. Let us not forget the PDP-11, whose 32-bit format is both BE (in bytes) and LE (in words).
