Hello from Luxembourg!
After a long absence I'm back on here, this time with a question. I am restoring the above, and now have the mechanism working fine, but for:
a small problem. When I put in a penny for 12 minutes (those were the days!) I get the full 60 minutes added, which is normally only there if you put in a nickel.
Anyone have any idea what might be going down here...?

Best regards

morgan
