Hey all,

Good news! I've located the problems with the machine and already have 
fixed the mechanical part. The elctrical problem is bad contacts in the 
edge connectors (a mere 850 pins...) and I got my first calculating 
results on paper in the form of the square root of 6. :-)

So ignore my earlier post on the scope probe path

updates of course on the blog.
