Corometrics 506 Monitor Schematics
These are copies of the original hand-drawn schematics. Got to
love 44 year old blue-lines.
Note that these are pre-layout schematics and so have some missing
pin numbers, reference designators, part number, and other
component changes. But the circuits haven't changed much.
