There are 2 clear generations of the 49g+, with 3 or 4 batteries (plus other details) but can you list the differences among the 3 generations you noted? Mixed feelings to learn there may be a new target to add to the collection... <sigh>

Thanks Bob for asking about this!

The 3 generations of HP49G+ I was referring to were:
1) 1st gen - initial release (keyboard issues).
2) 2nd gen - improved keyboard hardware but still keyboard issues.
3) 3rd gen - keyboard improved again, now same keyboard as 50g. Still uses 3 batteries. Identifiable by a thumb indent in the SD slot.

Perhaps I should refer to these as "revisions" rather than "generations."

Btw, all 49g+ calculators that I'm aware of use 3 batteries. The HP48gii had 2 generations that differed in the number of batteries, and as you mentioned, other details: (3 batteries, 128k RAM, serial only, released in 2003) vs (4 batteries, serial & USB, 256k RAM, released in 2006).

Thanks again!
