New transponder

So, Im sitting at my desk minding my own business when someone walks by and drops down a Gables G-3185 transponder panel and says I can keep it..:cool:. Anyone know anything about / where to get info regarding this thing?? I would love to make it work. I am familiar with using phidgets, so that is what I will use to iunterface it (unless there is something better for it). Any help would be appreciated.. The back of it has a single MS3112E 20-41p connector and a date of Aug 1971
