Narrative:

Asked by msp tower to take off runway 12R at taxiway M. Chart 10- 9 shows taxiway M, but chart 10-9C (dated earlier) does not, but it does show taxiway A7, which does not exist anymore since runway 12R construction was completed. The commercial chart airport analysis shows takeoff data for runway 12R/taxiway A7 and we departed runway 12R at taxiway M. This, technically, was not appropriate since we used runway analysis data for a taxiway intersection departure that did not exist.
