  Hmm...Z8530 is a [very nice] dual-channel serial I/O chip and the
Am9517 is a DMA controller...which, rather decidedly, makes it a
high-speed multiport serial card.

  The Z8530 is capable of synchronous and HDLC/SDLC operation as well,
up to 2mbps if memory serves. I have no idea what this particular
board was built to do, but it could even be something fancy like that.
