Here is my test board with the CD4520 and MC14495 – and some photos. Works very good and is easily done!

By the way, Frank: you got a new tab in my physical Lectron card file and all your circuits are still printed and are awaiting my tests and response – please be patient for feedbacks because I have a lot work to do before – sorry…
