Willi Huber, SWITCH, Limmatquai 138, CH-8021 Zurich, Switzerland
Actually the funny part here is that I have bought 3 of them on ricardo.ch about two years ago, and all three are labeled with a nice old SWITCH sticker :P
They are indeed fully functional running IOS 10.2.x with two AUI ports and two RS445 Serial ports ;) config registers are dip switches ;-)
