:-))) I've now got as far as getting my "development" box up and running with 
Arcnet and Ethernet cards in it, but I'm now stuck on the physical cabling 
side for Arcnet.. Do I use T-pieces and terminators, as in Ethernet??
So far, the green light on the card (LINK?) is on permanently, but the red 
light (DATA??) just flashes every second or so :-( BTW - there are no other 
machines on this LAN yet..

I hope it will be... An interesting experiment, anyway, and possibly useful 
if I ever want a network link to next door or something (probably too far for 
Ethernet).

Linux can use something called "ncpfs" - NCP file system. That enables it to 
mount Netware volumes and servers directly into the filesystem tree. It's one 
of the reasons I'm staying with Linux, rather than moving to FreeBSD or 
similar!
