ABSTRACT:
There is provided an information processing apparatus having a detachable first ROM cartridge in which a control program and other information are stored; an instructing device to instruct whether the control program stored in the ROM cartridge is to be executed or not when the ROM cartridge is attached; a control circuit to control operation in response to an instruction of the instructing device; a second ROM cartridge which is provided in the apparatus and in which a control program is stored; and a detector to detect whether the first ROM cartridge is attached or not. When the instructing device instructs not to execute the control program stored in the first ROM cartridge, the control circuit allows the control program stored in the second ROM cartridge to be executed. With this apparatus, when the detachable ROM cartridge is attached, the information other than the control program can be read out of this ROM cartridge and can be used for various processes.
