ArcNet and the Pursuit of Multiple Topologies

Any one ever use a network called KanNet (I think that's how it was spelled). It was around in the mid 80's. The early ones I used actually utilized both a host adapter and an external box (the network cabling attached via the boxes). The boxes were large (say 12"x12"x3") and the topology was a
ring running on coax.
