casio fx-920
| one of many, nicely made, wallet style scientific casios.
this one is similar in design to the fx-361, also
with rubber keys. it has the same 8 digit lcd display but less modes (2d
stats & bases are missing) but instead we are solar powered which is
nice to have.
the solar power works well, even in artificial light. casio made other solar styles like the fx-911, which is very similar to this in function but adds fractions which this model lacks. |
