    just found a whole bunch of them which may throw a different light on the subject.

    C4040 ES INTEL CPU RARE $800K So here's how it would go: Buyer pays $800K for chip. Buyer gets chip
    but doesn't dare power it (that's a whole different issue). How does
    the buyer know the chip is genuine? Is it worth more if it works?

    Now consider powering it:

    Will powering it destroy it? If buyer does power it and it tests bad,
    should he open it to find out if he was fleeced (risking devaluing it),
    just ask for his money back, or just sell it to the next sucker
    perpetuating the sucker train.

    I just don't see how one can see buying "collectible" micros a good thing.

    So, you'd pay $100 to get one ??
     
  7. I am having a hard time convincing my wife that we need to be patient
    and wait, until my garage-full-of-junk becomes Alibaba's treasure
    cave.

    If it came with a certificate of authenticity.......how easy would it be to clone
    a 4040 these days?
     
  9. **Those words probably apply to 90% of the people who read these groups.
    My collection of 1,200 baud modems, 386 laptops, 256k RAm chips, 28 year
    old CD players, Sony Beta machines, 20MB hard drives and valves are
    surely going to be worth something. Actually, some of my crap is
    (finally) starting to become valuable (I have a nice assortment of quite
    valuable vaccuum tubes). SWMBO calls it "junk". She knows nothing.
     
  10. **Probably. Never been a follower of sports. Played some, but never
    watched any. I do recall collecting cards from the local gas station,
    when I was a kid. Atlantic Petrol. As always, there was one, quite rare
    card. My mum probably chucked them out, along with my Superman and
    Batman comics. Arrggghhh!

    Lucky I've still got my Beta machines.

    Your "Chinese" is a common sidebraze used "in-house." Maybe the other
    packages were for engineering samples that went to outside vendors.

    The free shipping makes this deal so tempting. Wait, that price isn't in
    rupees?

    No, the buyer must not do anything that might reveal the item to be a
    fake. As long as the buyer has no grounds for such a belief, he can let
    the thing appreciate some more, and then sell it at a profit. The moment
    he knows it's a dud, his investment is lost.

    I agree. Does make me wonder what the two 4004's
    I gave away a couple years ago are worth

    w..
     
  15. According to this article, they were worth $212-$550 each in 2005, on
    eBay.

    http://www.chipsetc.com/computer-memorabilia-collectors.html

    Less than 25 cents/transistor, vs less than 1.5E-5 cents/transistor on
    a Gulftown i7 (about 2 million times more expensive).

    The Intel 4004 is probably worth a bit as well.....being the first uP.

    You could have sold an original 8086 CPU to NASA a few years ago for
    use in the space shuttle program! It seems they had to use old technology
    CPUs because of the exhaustive quality control regime involved in putting
    a shuttle together.

    Amongst the 'old crap' that I have discarded and now regret is a
    Texas Instruments SR-71 (I think) calculator (it did square roots!)
    and a HP 41C which I didn't intend to dump, but went missing during
    one of my relocations. I've still got the programming cards for
    the magnetic card reader, useless as they are!

    There is a MicroBee community out there as well, determined to keep
    Australia's own PC alive.

    I am really amazed how much interest the Microbee attracts after so many years.
    A very active group for what it represents.
