Ugly coat. I lost markings of an Intel MG80186 last time I met it.

| Bummer about the goop. I have encountered many evil goops. At least it wasn't the evil opaque epoxy found on the early pentium 60's. That stuff has no good solution and always removes the non-laserd text. As to the text on the back, nothing sticks well to gold. I have had several chips in the past that were in environments that altered the on-gold printing such that merely touching it with your thumb rubbed it off. This chip may have been exposed to such an environment but even if it wasen't gold is a poor subtrate for text. |

In response to your question #4 - for every fake produced, there is always a first example. Whether there are 10 or 10,000, someone has to sell/buy the first one.

I was refering to a fake made in the era of the 486. You are right, if it where produced today the numbers could be much less.

Good information on this chip. Nice find Lither!

I think it is dangerous to make any assumtions regarding fakes, and that includes assuming there was a first example of a cpu! People will do anything for money - take a look at the World-wide problem of fakes in everyday goods.

chip storage by such method was once very popular here esp in the pre-internet era
it is just like painting varnishes on the furniture
it makes the chip more durable to mechanical injury
but this method was abandoned soon after the internet became popular.
here is another example (another forum member LZF's current auction) how it damage the print
now i know how to remove it ... soak it in acetone > one hour |
