I just ran across some early Hayes Microcouplers and am curious what were
the first products manufactured by Hayes. The one here is labeled
"Microcoupler" has a hand engraved serial number of 216902. Unfortunately no
docs came with it. Also, anyone know if the serial numbers were sequential,
or were they some sort of code? Somehow it would seem if the numebers were
sequential, they sure made a lot of them!
