Hi guys,
wondering about the "stepping numbers" on C4004 grey...
I´ve seen 3 chips with the same number - one chip by me, one by cpu-zone.com and one from guest at chipdb.org with other package/print but same number. I always think to myself the printed numbers are like unique serials? 
Or is it like charge-number/volume-numbers?
The 4004 downside-print is one week different between the chips, i've seen.
My Chip is definitly not a fake - works perfect on 4004 board and the history of this chip is clear.
Any suggestions? |
