S = scientific ?
G = graphing ?
B = business ?
E = Europe ?
C = sCrap? ( you mad?) . Jokes aside: compact? Commercial? (For) Companies?
A = Alpha ? (prototype?)

"E" was generally for Engineering (31E, 32E, 33E), though there are clearly exceptions as the 37E and 38E are both business models. I think "E" was only used for the non Continuous Memory Spice models, plus the 94E (here, E denoted memory size)

"A" was actually not officially used by HP for any model I'm aware of. However, when another model came out with the same model number and a new suffix letter, the original was often listed with an A.

For example the first HP-10 was simply called HP-10. But when they introduced the HP-10C, references to the original model were often stated as HP-10A.

Someone once showed me some HP literature where the A suffix was used, but I can't recall the model... Anyone??

HP-44A.
