    摘要: A programmable electronic calculator includes two cassette tape recorders as peripheral system. An optional program or a data processed by the programmable electronic calculator is introduced into and recorded on a first cassette tape recorder. The first cassette tape recorder reproduces the optional program recorded therein upon request from the programmable electronic calculator. A second cassette tape recorder carries an audible message for operation guidance purposes. An interface circuit is provided in the programmable electronic calculator for independently controlling the operation of the first and second cassette tape recorders.

    摘要: A programmable electronic calculator operates in a programming mode, wherein a desired optional program is introduced into the programmable electronic calculator, or in a run mode wherein the stored program is executed. The introduced optional program is stored in a read/write memory (RAM). A mode selection switch is provided on a keyboard for selectively placing the programmable electronic calculator in the run mode or the programming mode. When a lock command is introduced through the keyboard, the mode selection switch is disabled so that the programmable electronic calculator will not be placed in the programming mode, thereby protecting the optional program stored in the read/write memory (RAM) from being unintentionally erased.

    摘要: 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.
