Do you mean this? http://en.wikipedia.org/wiki/Stripboard
If it's built on a stripboard then it will not work. Ronja is sensitive to
high frequency parameters of the construction.

What is port 0? If U66 and 67 (HC133) have 9V somewhere on them then they are already
probably dead - looks like a wiring mistake or regulator failure.
