    I forgot that I bought a BASIC-programmed Casio PB-100 'Personal
    Computer' with extra 1K or so RAM module and little thermal printer from
    Sheridan Electronics in about 1982. Amazing what I could do with it...
    filter calculations and everything!
    But when I need to calculate something, I still grab the fx-140 I
    bought in 1978. Battery life on a pair of alkaline AA cells has been
    averaging about 10 years!

    ** LCD or fluorescent ?

  4. Yep, they were terrific until there was a PC within arms reach of
    I just sold my Tandy PC-8 to a collector.
    I prefer the dual power models, you virtually never have to change the
    batteries. Two units I've got have never had a battery change in 15
    years. Probably should lest they corrode!

    My latest dual power one is an FX-991ES. Incredible functionality for
    something that runs on the sniff of an oily rag.

    Fluorescent.... Obviously it doesn't get a lot of use these days.

    I've got an fx-990 which is solar only. It's OK as long as I
    remember to hold it under a desk lamp when indoors!

    ** Alkaline AA batteries sure last a long time ....

    ....... long as you don't actually use them.

    Quite a lot of years ago, Eveready were advertising how their
    alkalines could sit around for a few years and still retain most of
    their charge.
    I wrote them a letter saying, "That's nothing, the ones in my Casio
    calculator have been there for 9 (maybe 10) years and they're still
    going strong when I use it!".
    A while later a Dolphin torch with alkaline battery arrived by post,
    with a letter saying "Thanks for telling us".
    I was impressed!

    A geologist mailed Union Carbide a photo of a PNG tribesman using
    a rectangular Eveready battery box as a penis sheath with a suggestion
    that they use it in their advertising. Needless to say they did not
    send him a lantern battery as a thank you.

    A very neat way of suggesting a new hat style to YKW.

    Is this because they are not reliable?

    I've still got all mine & they all still work. The biorhythm one's
    not a lot of use now because it can only handle years up to 1999 (it was
    made in 1975).
