Have 4 different Model 80's with the Anvil Stallion boards.  12 ports to a
card.  Another system, that will probably get approved next week will be the
guniea pig for their new 16 port card. That board is supposed to have an
aggregate throughput of 300kbs   per board.  We shall see.

Works well for our uses, multi-user office type environment.  I have heard that
they have had problems with high-speed incoming lines with uucp - eg several
telibits coming in at 19k simultaneously.

We set all at 38k and have had no problems in interactive use.  You can also
set the drivers up to be able to use 2 sessions per terminal up to a limit of
24 sessions.   Haven't had experience with the others.
