Is starting to piss me off lol

I emailed him telling him its a remarked NS part (and you can see the old markings even) and he essentially tells me I dont know what I am talkin a bout lol

I had a good laugh

I dont mind sellers sellin fakes, when they dont know they are fakes, or do know and they say so in the auction, but to KNOW its a fake, and pass it off as real, solely for collelctors is damn inproper

Where do you see the old markings?

Those ns chips marked by Intel do exist.
I bought some from demotronic.
I sold one to zizmo1:-)

I still do have two with different dies (small and big NS logo)

There must have been a production problem somewhen and Intel bought NS ones.
That's the laugh, I guess

That looks like the one you sold to zizzmo for $99?

$349 is a bit steep for asking.

Haaaaa!
I see the chip for auction is exactly the one Wendy got from me.
Here's the proof, one of my old pictures.
So either the chip is no fake or demotronic fakes chips. lol

Or I am the liar and all I tell here is paid by Wendy zizmo1.

Still the price is pretty high:-/

Did you see the prior auction?
Here it is, reserve not met at $101

No need.. I have a couple of those chips as well. I remember nearly falling off my chair when I saw zizzmo buying it from you.

I dont get zizzmo's buying strategy.. buys lots of stuff at collector prices ( and sometimes WAY over collector prices) then tries to arb with a few bucks.

Yes, sometimes you will get lucky when someone wants to throw their money at you.. but I dont see this as a sensible investment.. either you collect and trade or you simply source from brokers to sell on eBay or here to collectors. How does it work again.. buy low, sell higher?

Here is a NS 5202 which is similar, yet not the same as a 1702

Most likely the basis of the remark

Consider that Intel used NS as a second source (as well as Mostek, MFI, and AMD) during this period, there is no reason for Intel to remark a second sourced chip, they simply would have a customer buy from the 2nd source.

Would be curious to see a die photo.

[wepwawet]

it shows the NS logo

[CPUShack]

as it probably should.

If Intel did infact use National parts, it would be more likely that they would have bought dies, and packaged them, as remember packaging is almost always thrid party (NGK Kyocera, etc)

I think this is a Microsystems Internatonal Limited 1702 ( not A ) eprom.
I read it in a erased state = FF
I tried to program it on ProLog900 + PM9001A adapter failed showing not erased state ( FF )
Programmed it on a Modified Tenor 763 programmer Ok
The die shows 1601 and IIIL Logo !
Due to the different nature of the data output ( inverted via the 1702A ) i think this is a fake.
