 |
|
Hi!
I came across a fake Intel 386 with the i386 logo. I suspect that the i386 logo where not in use when this model where around (A80386-20). To help cpu-collectors spot future fakes, can we get together finding around which week Intel started using the I386 logo?
Ok, we got a theory. As in science we will now try to crack this theory.
If i state:
Week 2 in 1989 was the last week without i386 logo
Week 3 in 1989 was the first week with i386 logo
everybody agree?.
Start diggin´ your collection and tradebox and find your earliest chip with the logo. Post a image or datecode here.
Mine:

Here are a few.
The A80386DX16 L6190661E ( I assume is 1986, week 19)
But it also says 1985 1987 on the front. Could it be 1996, week 19? |

is most probable 1996, as it has the newer "DX"-logo und no "-" as on later Pentiums und 486DX4. |

I'd say the change was in 1989 week 3!

(i.e keep checking. Perhaps there are more than one production line at Intel or even different assembly plants where the week could diff.)

All my 386's obey to the rule.
PS: maybe could we make a rule about the new 386DX logo too?

My latest non-logo chip is 50/1988, the earliest with logo is 13/1989. This would support your theory. 
Best regards,
