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

It would seem simpler to just replace the reverse board with a newer one with the same functionality.

If at first you don't succeed, throw it in the spare parts box.
