[sammyc]

Have a look at what arrived today

Embedded i386sx that is... wow

[chipcollector]

I think that Intel 386 CX is a MILITARY chip!

[sammyc]

I believe it is a 'sample' of a military chip

[slava]

Why should you happen to think so? Just an ordinary PQFP it seems.

[sammyc]

Because o the military graded temperature.

[slava]

Examined the picture again but didn't find anything about temperature

[sammyc]

It was the site u posted i saw the info! lol

Good find.

Can you tell me where is it come from?

I know a collector from China has a set just like your.

I think it's a SAMPLE for customer.

[sammyc]

It came with a bunch of other bits... i'm assuming the guy must have worked at intel??

I was watching one of these a week ago. Went for $61 http://cgi.ebay.com/Vintage-Advertising-Salesman-Sample-Intel-i386-386_W0QQitemZ7209788890QQcategoryZ21092QQrdZ1QQcmdZViewItem
Thought that was you who got it when i saw this thread.

If you have thoughts about letting it go my max was $40 + shipping.

Thanks for the link, helpful stuff to know that.

[CPUShack]

Its not military, it was however available in military temperature ranges

[slava]

The link I posted clearly indicated four different types of packaging of this cpu. You have three of them - PQFP, SQFP, and the die.
The military one is not present.

[sammyc]

OK, didn't understand when I first read it. cool!
