Many years ago I saw a ham in the St. Louis that had tapped into the back of a ST-6 to a Radio Shack CoCo computer. Or the other way around CoCO to ST-6. I don't think it was Joe, K0BX May have been KB0TT (now W0JBC). I really recall who it was now. Been to long ago. Does anyone know how it was done? John, W0JAB Louisiana, Missouri
