Token-ring thingy majigy

Kate Godfrey writes in an email: " As I was recently rummaging through the lab for a token ring type 1 cable for some industrial art I decided to make we had a ''fascinating conversation'' for which we had no conclusion. Do you remember a sort of square box which had around 4 type 1 connections and one in the middle to stack to another one of the boxes. So you could sort of chain together a TR network without a hub. Any idea what that was called? " Anyone recall what the thingy majigy was called.   I think it might have been something like a four-port hub???
