I had a full explanation from Intel somewhere what the numbers mean, but I cannot seem to find where it is now...if I do I'll post it.
This doesn't answer the A/B thing, but here is how to read a batch number.
Code:
Example: L707A723 ---
1st letter or digit = plant code: (Malaysia)
0 = San Jose, Costa Rica
1 = Cavite, Philippines
3 = Costa Rica
6 = Chandler, Arizona
7 = Philippines
8 = Leixlip, Ireland
9 = Penang, Malaysia
L = Malaysia
Q = Malaysia
R = Manila, Philippines
Y = Leixlip, Ireland
2nd digit = Year of production: (2007)
3rd & 4th digits = week: (7th week )
5th - 8th digits= lot number: (723)
10th - 13th digits = serialization code (---)
