 |
|
How do i read the markings on the Cyrix FasMath?
1992 week 27?
1993 week 13 or 1991 week 39?
Edit:
And this 486? -94 week 23 or -92 week 32?
AF4232V
Is 2V perhaps 2 volt?
Edit2:
A Cyrix Cx486 marked H1LP508J?
Edit3: 
A 6x86-P150*GP marked G8DC5621C?

You can read it from left to right... 
Well, I'm not 100% sure, but the 3 last numbers gives you date code.
ex : First Cyrix FasMath : AAE227A -> 227 -> 27/1992
The same for the SLC : 32/1992 |

Thanks!
Infact i looked there but it states 6x86MX and i had a plain 6x86 but that does not seem to matter then? last three digits = YMM.
