The calculator experienced a Fundamental interpreter, MEMO function, a method collection. The buiIt-in 8 kB storage could be expanded making use of the various Casio RP-8 (8 kB) or RP-33 (32 kB) Memory expansion modules. An optional Casio FA-6 user interface board provided a cassette cassette recorder connection, a Centronics printer connector and an RS-232C interface. The calculator could printing information and listings on any Centronics printing device; printing images required the Casió FP-100 plotter-printer.

Later on, Casio launched the FX-880P, which had 32 kB built-in memory space. With a RP-33 growth module, this design could end up being upgraded to a total of 64 kB.
The battery requirement for the Casio Forester FT500WC is different, although from the outside this watch looks just like the Forester FT500WVB. The FT500WC watch requires two batteries, one battery to run the watch (the SR920SW) and the other battery to power an LED light for the watch (the CR1616 lithium battery).
The storage layout will be:
- 0000-00FN Screen storage
- 0100-01FF Set aside for internal functions
- 0200-02FN INPUT Buffer
- 0300-03FY CALCJMP, VALF Barrier
- 0400-04FF Set aside for IN/OUT/CALC settings (CALC$)
- 0500-074A Set aside for inner features
- 074B-0752 Appropriated for storing the user PASSWORD
- 0753-175A Set aside for inner functions
- 175B-175C Vector aiming to MEMO memory space start
- 175D-1FElizabeth4 Arranged for internal features
- 1FE5-1FFF Vectors pointing to G0-P9 memory begin
- 2000-9FFF User memory space (shared by MEMO and P0-p))
- A000-BFFF Replication of 0000-1FFF
- C000-DFFF Repetition of 0000-1FFF
- E000-FFFF Replication of 0000-1FFF
Storage region A000-FFFF was either accessible as consumer storage (if enlargement was present), or would merely do it again the items of 0000-1FFF
A several glitches are usually:
- POKE 1867,0 → would delete any consumer Security password
- POKE Look(8027)+256.PEEK(8028),32 → would recover contents of MEMO after a RESET ALL
- POKE PEEK(8027)+256.PEEK(8028),26 → would hide items of MEMO, very much like a Reset to zero ALL would perform, but without dropping the applications
The internal function collection was programmed in BASIC itself and could be extracted with a BASIC decompiler.
Any functionality in the library can become carried out from a normal BASIC plan by making use of GOTO 'LlB0:NNNN' whére NNNN is definitely the functionality quantity (y.gary the gadget guy. 5010 for perfect factorization). The order GOTO 'LIB0:0400' executes a self-test plan.
Character types 252 to 255 were user described. They could end up being defined by giving the control DEF CHR$(n)='HHHHHHHHHH' whére n runs from 252 to 255 and the L's are 10 hexadecimal digits (5 bytes). Every byte identifies the -pixel design for a line. Since a line is usually 7 pixels higher, the least significant little bit of every byte can be disregarded.

Thé CHR$(26) would power up a different character set for Katakana and Kanji heroes. CHR$(27) would deactivate Kánji.
Viá a serial cable the loan calculator could link to a PC or to anothér Casio FX-850P, enabling the exchange to MEMO and kept programs.
