Limitations

• Although the machine has 64k RAM, the ROM is copied into RAM so the maximum program size is around 20k
• Anything graphical has to go via the sub cpu. Communication with it is a little slow so displaying anything on screen is sluggish
• Not all subcpu commands are known, so graphics are not available

CP/M

No specific libraries are at the moment available for the Casio FP-1100. A disc image suitable for use with an emulator can be produced using the -subtype=fp1100 option:

zcc +cpm -subtype=fp1100 program.c -create-app
