Hello all!

I am working on resurrecting a machine that currently has a heidenhain TNC 155 control, and was wondering if someone could scan some high resolution images of the the wiring section (4.3) in a TNC 155 or 151 service manual?

This section consist of four pages and details the pinout information between the controls backplane and the plug-in borads. I am specifically interested in the third page and connectors J4 and J5, which interface the analog board (glass-scale input) with the rest of the control. I have been able to find a pdf version of the service manual, unfortunately the scan quality makes the text unreadable. A good quality scan of this would really help me move my project along.

Thanks in advance !
