Hi I have an Early Williams reversing unit. Anybody have an non working board or a Schematic on these or know where to find them. A little research has produced that these board are based on a design by Kenneth and David Ott. A sort of simple schematic was published in a 1994 patent. I am looking for the values of the components connecting up to the HFC4017 Counter chip, see Included Picture components with a ? are the values I am after.
Any Help is very much appreciated
Thanks
