not really.

contemporary controls, who manufacture the pci arcnet cards
supply the drivers for windows. we have drivers for the com20020
NIC for our embedded os, and the chips a as cheap as... well, old chips.

our bridge and cards are just a different software on a fairly standard
modular card which fits in our 3u rack system.

if anyone wants detail contact me off-list, this is already creating too much noise.

my real reason for asking was to gauge interest in a plan9 arcnet driver
as i am perfectly placed to write one, but it seems there is no interest at all.
this is a problem thought, i have plenty else to do :-)
