The FX-700P is quite the same machine as the [PB-100](/museum/casio-pb-100/), but is a member of the more scientifically oriented FX product family. Consequentially, it is called "Programmable Calculator", as most FX family members.

It has 2 KB RAM, i.e. it was equipped with two HD61914 RAM chip instead of one like the PB-100, but no further RAM expansion was ever made available.\
Moreover, the mathematical functions (SIN, COS, etc.) were assigned to the keyboard, by means of an additional function key. Apart from that, the hardware of the two machines is identical.
