One could probably guess those newer codes based on the previous list, although it is not totally consistent. 
(There is an AE and a CE, but no BE).

Many lustra ago when I was in QC at Texas Instruments, the build revision letters were marked on each circuit board.  They would not use I, O, Q, S, X, or Z since some of those could be mistaken for something else.  The mnemonic I came up with to remember those letters was Indians On Quaaludes Seem Xtra Zany.    ;D

Heavens Abilene, I like it!

Were you around when the gov,t rejected huge lots of a particular TI chip from Thailand?
It was a peculiar chip, used mainly in wing mounted missles. They seemed ok, but after installation, when the jet jockey pushed the go button, they did not so much fly as plummet....
