My brother works at a graphical company and have scanned the original "Owner's manual" and the "Circuit diagrams" for me,
and made PDF files. So it is from high quality and ready to print it out on paper.

The  owner's manual  is 35 pages and 3,6 MB
The circuit diagrams are 6 pages.

Filters

The 110F has a trasister ladder filter.
This filter was a great invention of Bob Moog.
The circuit is constructed by transisters conected like a ladder.
This circuit is used in lot's of Moog synths, through '60s Moduler till '80s Memorymoog
and is famous for the fat sound.
