I totally agree... unlike the poster above (sorry but 90 kegs?? not a hobby anymore) Golf, Guns, Quads, Cigars and Scotch are my other hobbies.....I stopped adding up what my "hobbies" cost me a long time ago :)
This is the schematic you want. You'll need a 595 shift register. No reprogramming of pins. Should be able to wire it up and have it work. I'm leaving on vacation for two weeks tomorrow or I'd throw this together and test it out. If nobody has by the time I get back maybe I'll put it together.
