AbstractA miniature computer has a main section which includes a central processor, a read only memory storing a monitor program, a random access memory for executing the monitor program and a controlling circuit for peripheral equipment, and a hand-held controller electrically connected to the main section through a flat cable, the hand-held controller having a keyboard and display device such that the keyboard has keys of numerals 0 to 9 and the alpha characters A to Z for enabling data in the form of symbolic language to be input according to an assembler program. The assembler program is stored in the read only memory and the symbolic language data is converted to corresponding machine language. The hand-held controller includes a key input system which utilizes encoders rather than mulitplexers to detect and transmit key input data data to the main section.
