The cable is designated RG-62, but it's 93 ohm cable. Cards could be connected to an active hub or a passive hub. Passive hubs required 93-ohm terminators on the unused ports. But with an active hub you're all set. I have a couple of cables with BNC connectors, and I think a few left-over crimp-on connectors that you're welcome to have for the cost of shipping (or pick up in Berkeley, CA). Write to me offline. I got rid of a heap of arcnet stuff last year, alas. I think it's all at the Alameda County Computer Resource Center :) By the way -- how about DVD's via pneumatic tube? Now THAT is a high-bandwidth medium. I can sell you some pneumatic tube equipment too :) Brian
