    Re: HP 48GX Sight Reduction Programs
    From: Dan Hogan

    I own an HP48GX. I have given up on using it since Hewlett Packard announced
    that they are getting out of the calculator business. The programming of the
    HP48 also drove me nuts. I now use a Palm m100 for navigating, there are more
    navigation programs available for the palm OS. I also use a pair of HP
    32SII's, one for sight reduction and one for DR.
    Probably the best sight reduction programs for the HP48 are the ones written
    by Tom Metcalf:

                                    NAV-P8S4 for the sparcom card --
    Do a search on "Navigation" at hpcalc.org. It will list just about all the
    HP48 navigation programs available.
