PURPOSE:To realize various types of calculation with a miniature microcomputer by connecting ROM memorizing the basic program for actuation of CPU to CPU, connecting the programable interface to the printer and then connecting the enter key to CPU respectively. CONSTITUTION:Various keys such as ten-key 4 and others are provided at the right side to the center of the upper plate of case 2, and printer 10 is installed at the right side of each key. Then programable interface 13 and enter key interface 14-a are connected to CPU12, and ten-key 4, code type key 7-a and others are connected to interface 13, along with selection key 8-a and others connected to interface 14-a respectively. Furthermore, ROM16 memorizing the basic program for actuation of CPU12 is connected to CPU12, printer 10 is connected to interface 13, and enter key 6 and reset key 9 are connected to CPU12 each. In this way, the computer is miniaturized and with easy performance of various types of calculation. |
