    Roland MB62H195 gate array

    This is one of Roland's several multifunction I/O gate arrays including
    built-in address latches and chip select decoders. This one's
    particular features include both an LCD data FIFO (write-only) and a
    parallel/serial converter for a µPD7001 ADC (the clock for which is
    based on an internal oscillator).
