RE: The bizarre Casio FX-840P
I found a bit more information on the FX-840P just now. It seems it is a sister to the FX-860P which did come with 32K internal RAM! These seem to share the same PCB as the FX-850P/FX-880P and an earlier revision of the HD62002 processor. The FX-860P does seem to have a different ROM, i.e. more built in functions so maybe it all comes down to the ROM?
