  The PC adapter can be used in a file server or a work station while the
  PC-WS adapter can be used in a work station only. Different drivers
  must be used for the National & the Fujitsu chipset cards, they are not
  interchangeable. Fujitsu adapters may be used for either 8 or 16-bit
  Fujitsu cards, while the National chipset cards require a different
  driver for an 8 or 16-bit card.
