casio fx-310

the fx-310 is functionally the same s the fx-350, both have 8 digits (11 internal) as well. not sure why there were two models. perhaps this one is slightly newer or possibly designed for different territories.

i prefer this style to the fx-350, with the on switch and model button at the very top. like the fx-3500p also in this style.

this model is quite thin and usually lives in the casio wallet-style case. it is powered by two G10 cells (V389) rather than G13 (lr44).
