    I can't find anything on that site that says they sell the actual cards.

    Still, it's impressive that you can still get this stuff. They started
    using this technology circa 1890. I suppose they can read cards a little
    faster now...

    Dear Benjamin,

    Go to the index:

    http://www.cardamation.com/index.html

    Then click on Punch Cards/Supplies.

    $32 per 2000 cards, minimum order of $50.

    I believe Mr Brown's choice of words is correct in that
    while one might indeed make or buy a shaft drive, there's
    little point, chain being so much more efficient. Perhaps in
    the sense that vacuum tubes are obsolete, which doesn't
    preclude another tiny but active market. Or straight razors
    with leather strops.

    Now that you mention it, that actually seems like a reasonable use for
    them, since they can be read by humans as well as machines, and they're
    somewhat less vulnerable to, say, EM radiation.

    From an interesting history:<

    " By the time of the contested presidential elections of the year 2000, it
    was estimated that 1/3 of the polling places in the United States still
    used punched card ballots."

    Dear Jobst,

    Of course no one ever saw me dangling in your precinct in
    California.

    Although I'm from Massachusetts, Mr. James left me dangling
    interminably in Paris in "The Ambassadors."

    Too late. The Bush fiasco in Florida killed that possibility. I also
    believe the punch card ballots were far better than any replacements,
    especially the no-backup, not tamper proof, electronic voting that has
    replaced it in this area.

    Too bad, we should still be using them had not the brothers Bush
    messed with the system. The hanging chad was just a cover for the
    willful miscount in Florida. If you believe the hanging chad story,
    you'll believe almost anything in politics.

    1 a : no longer in use or no longer useful
    b : of a kind or style no longer current

    (1a) No, it's still in use and still useful.
    (b) No, it's a style in current production.

    How can it be obsolete when it's still available?

    Hmm. Buggy whips are still available, as are outhouses, hand
    pumps for wells, tubular tires 8^), 8-track tapes, vinyl LP's,
    and many other obsolete things. OK, maybe there aren't any
    8-tracks still available, I really don't know.

    You bring up a good point: a lot of obsolete items, even eight-track
    tapes, are still available from specialty distributors for collectors.
    Shaft drive for bicycles is a different issue. The availability of
    shaft-driven bicycles has waxed and waned over the past century, much
    like that of tandems and recumbents, but its continued tenacity in the
    market seems to preclude any pronouncement that it's obsolete.

    Obsolescence is the act of becoming obsolete. Obsolescence and
    obsolete are two different words and have different meanings.

    At one time a shaft drive made perfect sense, chain being
    crude. One of the most beautiful and better handling bikes
    I've ever ridden was a 1910 Pope in cromovelato green with a
    shaft-drive fixed. Modern chain obviates that sort of thing
    completely. Lighter, more efficient, no gear lash, simpler,
    cheaper. Need I go on? Shaft drive is obsolete. Pointless.

    Still beats the solid state devices in reliability and delivery in ultra high power output applications.

    I'd prefer more specificity than Devices and since the function is pretty similar to a FET, why not keep the same suffix?

    How 'bout moving Encapsulated to the lead to avert that consecutive E pairing and come up with a more easily pronounce acronym such as:

    ESDEFET?

    If I Cover the Duck does that make me a quack?

    Is this available as a retrofit kit or merely as a complete bike?

  20. the shaft drive was a shafted wal mart type "dirt" bike selling for
    $300.
    now if this bike's shaft lasts 5000 miles
    and one divides the dirt/pavement related chain/cluster cost over 5000
    miles into $300
    but if the shaft lasts 7500 miles then...

    now what?

    well now how long does it take to exoletive deleted that shaft off the
    ep hub and put a new tube in?
    baby how long till the sun goes down?
