You write:
"I think the misorder of the suits might be corrected by flipping over the chip. I don't have the two chips here, so I might be wrong. If not, I would guess the LOT and ROT (or SSL and SSR) probably corrispond to the order. "

Flipping over has the same effect. That was my first thought too. I will have to search for others of the same mold but since I'm a newbie I probably won't have enough for a fair sample. I think I wont even look, just wait a few minutes till someone gives me the answer.
Thanks
