It's been bugging me for years so I'll ask...............
Anybody have any different variations of the chip in the package?
I know of 3 "different" variations. Same back to package.
Chip.
Holed chip.
Holed chip with no writing. Just put in the packet the wrong way around I assume.
I'm curious to know if any others out there?
I suppose an unholed chip with no writing is a possibility?
Anyone?

Thanks.
