From issue #1 of Alpine/Nordic: The Journal Of Unconventional Skiing. It was published by Alpine Research Inc in 1981, by the folks making Ramer bindings. I am not sure, but this may be the first, and only issue, published.
My first ski mountaineering setup - 1979 to 1981 - working for Colorado Outward Bound was a pair of Rossi Strato alpine skis, mounted with Ramer bindings, used with leather Galibier double boots. (In fact, I still have the skins that I used with this setup, and they do double duty, as backups for my pomoca race skins on my Dynafit PDG race skis.)
