Sweet!  :-+ :-+

TiN has done an outstanding job, but hopefully these can fill in any blanks.

These also work. They are the repair manual and addendum.

TiN and I have been pouring over these since finding them yesterday, but good find anyway! (Note the teaser yesterday in this thread).  I wonder how long they have been up there undiscovered. The main page with links is:

Well, I did search the domain name in the forum before post this thread, but found nothing.
This forum is the original source  :-DD. My friend sent me the PDFs yesterday, and I Googled out the online document.

Thks for the great discovery.8)

Did someone go through the schematic of the analog board and the ADC?

The ADC Integrator have one postive and two negative integration inputs in addition to the signal integration input. All with different scale factors. I thougt that a multiramp should have symmetric inputs. Or do I miss somewhere a signal polarity switch?

The AD buffer only seems to supply gain x1,x2,x5,x50 not polarity...
