          Now  there is  an adapter  that lets  you initially  connect your
          network  with one  type of  cable,  and later  switch to  another
          without  the major expense of replacing your adapters. Artisoft's
          AE-2/T Ethernet adapter offers you this flexibility by supporting
          two kinds of Ethernet cabling. 

          The  AE-2/T   adapter  lets  you  cable  your  network  with  the
          affordable  unshielded twisted-pair cabling. Then all you have to
          do to make  your network connections  is add Artisoft's  Peer-Hub
          concentrator, or any other standard  10BASE-T hub - or upgrade to
          thick  coax cable,  which extends  network lengths  to up  to 500
          meters and 100 nodes per segment. 

          This adapter  is 100%  downward compatible  with Novell's  NE2000
          drivers. Plus, it's  more affordable and offers  better features,
          which makes it the smart choice for LANtastic networks -  as well
          as the smartest choice for Novell and other networks. 

          Like the NE2000, it offers 16K buffer  RAM - twice as much RAM as
          most other  adapters  offer.  But  only  the  AE-2/T  adapter  is
          upgradeable to 64K. So you can get information off the cable much
          faster, and your computer can move on to other jobs.

          It  even gives  you increased efficiency,  with more  IRQ options
          (Interrupt  Request   Lines)  than  most  other  adapters.  These
          additional  IRQs can  be  used  by AT  class  machines or  above,
          leaving you more free IRQs for other hardware devices.

          With  an  optional  Artisoft  PEROM  chip installed, you can boot
          up  a diskless workstation  from a  network  server.  Each  PEROM
          chip  contains software instructions that locate  the boot  image
          stored on the server and boot up the diskless workstation. What's
          innovative about this PEROM  chip is   that  its software  can be 
          reconfigured or updated  by diskette, which  means you don't have
          to replace it,as you would other ROM chips, which saves you money.

          The Artisoft AE-2/T Ethernet adapter can be used in either 16-bit
          or 8-bit slots  and automatically senses  between these modes  to
          switch for higher performance. It  offers a 10 Mbps transfer rate
          and is in 100% compliance with IEEE 802.3 Ethernet standards.
