Modular Patch Diagrams

[Mark Space-Ratio]

Does anyone have a patch diagram that would allow me to synthesise the sound of the classic 'boing' using hardware modulars.
There doesn't seem to be a wider patch diagram resource that I can find along the lines of Allan Strange's book. Of course I may be wrong but could someone point me in the right direction.
Does anyone have any interesting diagrams?
cheers
