Chip identifiaction help please.

[gm5150]

Here are the chips that came with my car when I purchased it this past February.
Is the top one still usable or any good?
The two in the middle, anybody know what they are?
The bottom one I think is stock ship?

the duttweiler chip is probably usable, but its for a turbo TA, it may not function properly in your GN. the 2 in the middle are probably usable....but i dont know anything about them.
but with the tech changes i would have eric at TT burn you a new chip that is up to date and you know it will be good!
