- (A) You need to reverse 180 degrees: 90 degrees is a right angle,
- and there's nothing good to come out of that!
- (B) There's no special directionality to the head: the direction
- is provided by the motor, so
- (C) To read flippies without flipping, you would have to reverse
- the motor and read normally, or read backward and translate, which
- (D) Is a *whole* lot of work, when we have a lot more useful
- hardware projects we could be doing! I mean, to save the trouble of
- flipping flippies over? How many weeks of hard work to save how many
- minutes of minor inconvenience? 8-)#
