I ran this way at home for two years.  Knowing that my serial port speed
wasn't as fast as it could have been nagged at me for a while so I spent too
much time and money to learn that the magma cards don't work in 1.4[.{123}]
or 1.5.  I've tried both old and new revs of the Magma 2+1 Sp cards.
  
I never tried with an earlier version and I know the web page says it works,
but it just doesn't and I never had time to mess with it.  If it did work it
could provide a 115k (or faster) serial port suitable for an external ISDN
TA as well.

I have a classic (16M RAM/200M disk) in a commercial setting doing just this
thing.  I was able to support sustained throughput at >3Mb/s for 8 hours
with ttcp testing.  The 3Mb/s limit was likely do to 10bT speeds and not the
box.  Never had a problem with it though the owner wonders why that box
works but products sell for so much more.
