As seen in numerous episodes of Star Trek: The Next Generation.

I think I stole this from Frank Cerney.

This is a very nice replica of the Iso Chips seen in TNG. I believe it was made by Steve Horsch, though that is just speculation based on other replicas I have seen out there. I think I got this from Frank Cerney. A while back, I was researching doing a run of these for my own filthy purposes, and I asked Frank if I could borrow one of his to use as reference. I took these photos, then packed it away in a box, which promptly got stashed in my Raiders of the Lost Ark-esqu storage space. Sorry Frankie! I still love ya, baby!
