The My Brain JD-700 and JD-800 were the first personal computers from Matsushita Communication Industrial (today, the Panasonic Corporation) and went on sale in 1978. The computers ran on an 8-bit 8085 MPU and used an extended dialog-based version of BASIC and CP/M as their primary software. The JD-700 had a five-inch floppy disk drive, whereas the JD-800 had two eight-inch floppy disk drives and three I/O ports. The personal computers were mainly used for business applications such as payroll calculations, production management, and inventory management. It could also be used as intelligent terminals.
