This rare Aristo M 400 was sold by Aviation specialist Jeppesen mid of the Seventies. Please notice that this is not a Flight computer like the later avstar and prostar products manufactured by Texas Instruments, just a nice calculator for the pilot. Interested in Aristo calculators? Don't miss the rare M 27.
