ABSTRACT:
An electronic-type computer in which programs may be entered from a key entry device into a Random Access Memory in which they are stored, and those programs may be read out from the contents of that Random Access Memory and executed, while, in addition, programs may be written and stored ahead of time in a Read Only Memory, and those programs may be read out from the contents of that Read Only Memory and directly executed. The previously written and stored programs in the expandable ROM do not utilize the RAM user program area, and the large volume of programs contained within the expandable ROM can be directly executed. In addition, the user programs and the programs in the expandable ROM may be linked together and executed. Furthermore, it is unnecessary to give instructions for the programs in the expandable ROM to be transferred to the RAM.
