          The  Artisoft AE-3  Ethernet  adapter  supports  three  kinds  of
          Ethernet cabling --  thin, thick, and  twisted-pair.  Start  your
          network with the inexpensive twisted-pair cable found prewired in
          newer office  buildings.    When your network expands  beyond the
          cable's 100-meter  capability, you don't buy new  adapters.  Just
          connect thin coax or thick Ethernet cable to your AE-3 cards.  

          Suitable for use  with any Ethernet  system including  Artisoft's
          LANtastic  network,  the AE-3  adapter  is as easy to install and
          set up as the LANtastic system itself.  The adapter is compatible
          with   Novell  NE2000   cards  but offers more  features such  as
          providing additional IRQ  (interrupt request) lines  so  it won't
          conflict with other expansion equipment.

          Included with the adapter  is its software driver containing  the
          Artisoft NetBIOS standard and  a  user s manual  written in plain
          English.

          As your network grows, the most efficient use of office resources
          comes  through  the  peer-to-peer    LANtastic  Network Operating
          System.  It makes file and equipment sharing easy by enabling any
          workstation on the  network to also be  a server.  In  a diskless
          workstation, the AE-3  adapter allows you to   boot your computer
          across the network with Artisoft's programmable PEROM chips.  And
          in an office  where portables need to connect to the  network and
          sudden  expansion  needs   are  common,  the  Central     Station
          connectivity platform is an open port to an Ethernet system.
