Well, the SC looks for a series of 1's and 0's for the header tone. Yes, an $AA is 10101010, and adding an extra 0 bit would be just fine, but a series
of $55's and then a $54 is so much easier to implement :) It's the same thing though. At any rate, I believe that the $55 was used originally because the value used for checksums in the tape format is $55.
