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.

hello all,
I'm in the process of repairing our 101 but i hit a solid wall finding
out whats wrong with it. are there people with a working copy who could
do some measurements on their copy?
Unfortunately i have no schematic of the electronics, only the mechanics
and PSU.
I have made a crappy video of the scope trace of the delay line input
and i'm very interested in a video of a working machine's delay line. :-)
The video is here: http://youtu.be/llpwjGeldt0
and a partially repairlog is here:
