I have three cards, atmega 128, a dik , and a bev. how do I identify the two factory cards? Is the 128 still useable? Thanks

the 128 is still good and will be forever. (well maybe not forever but there is hi hopes it will survive n3)

The other two cards have small numbers in the bottom left and right on the barcode side. If you post those numbers NOT THE S00 number we can tell you what they are perhaps.

what your looking for is aa-07, or aa-06, sw-04 etc. there is also a 102p0007 or something number sometimes. Just tell us the numbers where it says nagra id and someone will probably know.
