    Older PA-RISC machines have at the front panel a LED
    which shows machine load (4 LEDs), heartbeat (1 LED),
    SCSI activity (1 LED) and network RX/TX (1 LED each).
    This panel is programmable via software and a nice and
    consistent linux kernel and userspace API across the
    architectures is IMHO a good thing.
