Recently I got a few Cyrix 5x86.
They are together in same package.
Three of the fronts are not printed, only handwritten marks.
Two have dates on the back and the other is blank.
No test.
Who has any clues or opinions. |

The one without writing on the back is also unusual because it doesn't have the glue outline around the die cap.
Strangely the one with the earlier production date seems to be ready for sale. Maybe the ones with the week 48 markings are for testing 4x multipliers? If possible you should test to check that, and if any are S1R3s rather than the usual S0R5. |
