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.

I should hope so, but at $800K for a 4040, I figure it is about $799.9K over priced.

So, you'd pay $100 to get one ??

 

**This is very interesting. I have a 256k printer buffer I purchased
from you a few years back, that may be worth a fortune one day.

Yay!

 

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?

 

**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.

 

**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.

Schrodinger's chip?

 

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

w..

 

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.

It was easy to hack.

 

I have two Alpha SBCs, but US dollars are required.
