I'm not so sure that IBM doesn't still make the broadband cards for AT class 
machines.  Last summer we refitted our machines with the newest adapters from
IBM, called the PC Network Adapter II.  (The MCA version of this card is the 
PC Network Adapter II/A)  
   Broadband networks are NOT interchangeable with ethernet and acrnet-type
networks.  The token ring network is much more compatible with ethernet networks

than broadband systems, the difference being that the carrier is "modulated"
on broadband, and is not on baseband - or token ring.
  As far as availability, they *SHOULD* still be available from IBM via their
direct order system.  It is listed in the last equipment brochure I received
from them.  However, if you're looking for the original model, you are out of
luck as far as new equipment goes.  You're probably better off going with the 
new adapters - they will work with the old ones, and they operate 200-300%
faster.
  One caveat, with the new adapters, you will also have to acquire the IBM LAN
Support Program, which is the set of device drivers to operate the card.  The 
old card had this in ROM, but the new cards do not - I understand for reasons
of flexibility.
