First, I know approximately nothing about old Intel chips, so forgive
any incoherence.
A friend of mine just came across a couple of Intel 8008 chips.
Apparently, some ebay sellers think they're solid gold.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260099837541
As far as we can tell, that's what Mel has.
Anyway, I told him I'd try to find out what it's actually worth and
whether anyone here is willing to pay whatever's reasonable.
He also has some later 8008s without the gold cap.

hehe wishful thinking on the part of the seller. I have one in a PCB
rescued from a piece of HP (voltmeter iirc)
perhaps I should put in a bank deposit box

So, is anyone counterfeiting them yet? It wouldn't surprise me - after all
presumably people don't generally sell them as "tested and working"
anyway...

It might be the first microprocessor, (i4004 is just a controller...), but what really
made the microcomputer possible is the DRAM. Why dont people collect i1103's ?

You could probably get a nice plane ticket.
There is a "missing link" Intel RAM that many chip guys lust for. I do
not recall the number - 210something.
If I look thru my records I can probably remember, but I have too many
things to do right now.

I wrote DRAM, but actually meant semiconductor RAM, so also SRAM.
To put it in anther way : there was never a core based homecomputer.
The i4004 is a controller, at least to me, because it is dependent on a specific set of
supporting ciruits (4001,40002 and 4003).
The 8008 is much more general purpose.

I have a Tektronix cartridge tape drive (ca 1977) here using an 8008.
There doesn't appear to be any other 8008-specific chips in it.
A 2708 EPROM, 8316 ROM, 2 2102 RAMs, 2 GI LSI chips of unknown function.
The rest is a mess of 74 TTL.
I'm reasonably well-acquainted with the 4004 family chips and their
inter-communication and execution cycle, but not so with the 8008.

I would make the distinction on the basis of what you can do with it.
A college classmate of mine built a 4004 based microcomputer in 1974
that was a general purpose machine, just as the early 8008 basd
micros. I would certainly call his creation a microcomputer, not a
controller. It certainly was hairy -- about 100 chips on a large
wire wrap board.

Well, I would, if I could find plenty of them at a sensible price. Of
course I 'collect' them to use them, I'd fill up the second memory PCB in
my 9830 with the 32 chips it doesn't have (2K words more of memory), and
add the control locig. Maybe also make a memory ezpnasion PCB for the
9820 (it's indentical to the stnaard memory PCB, and contains just 16
1103s and some decoupling caps IIRC).

And when he sells it for 1300 bucks, he can buy a lot of crack, and
laugh all the way home.
The "super-price" philosophy of surplus and antiques actually DOES
work, but the sellers must have balls of brass and infinite patience.
And a lot of stock with little overhead.

Was there not a sale of a "one of everything Intel made" collection in
the last year? I wonder if this guy is trying to recover from the silly
price paid for that collection by parting it out?
I see these chips have no solder on the leads, so are probably pretty
pristine specimens.
I wonder if a really workable counterfeit could made from other than a
different chip with new paint? Hopefully that won't happen, but with
this kind of money involved who knows.
Also, these high dollar listings he did are foolish as he has to pay
real money to list them even if they don't sell. I dont know if there
is a discount by setting up as a store, but epay has gotten expensive if
you pick a price anymore, rather than starting the auction at $1.00 and
letting the item float.

of an 8008, not an unreasonable idea).

According to some (fairly) reputable sources, chip counterfeiting
isn't all that uncommon:
