RCA connector
On the back of the device you could also find an eight-pin DIN connector for a cassette recorder with which you could load programs at 2400 bit/s. Then two connectors for video output, an RCA connector RF output and an eight-pins DIN connector that could output NTSC or RGB video. The JR-200UP variant outputs composite PAL and RGB. Two other connectors provided a centronics compatible printer port, (supported by Basic with LPRINT, LLIST and HCOPY, a "screen dump" command) and an expansion interface port. The expansion port connector also had signal lines for an RS232 serial connection which Basic supported with several commands, but its main use was to connect a 5¼-inch floppy disk drive.
