math error in old air traffic control book
From the book "Air Traffic Control: The Uncrowded Sky" by Glen Gilbert (an ATC classic). The book is from 1973, but even then transponder codes were 4-digit octal numbers. 1029 would not have been possible.
Perhaps HP saw this in 1974 and therefore allowed 0-9 in octal -> decimal conversions on the HP-65! |
