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.

PCB2 Sh2: Pressure, Temp,  and Isolation
PCB2 Sh1: Respiration processing
PCB2 Sh2: Isolation barrier demod
PCB3 Sh1: ECG processing
PCB3 Sh2: Pressure processing
PCB4: Waveform Display
PCB5 Sh1: Numerics Display
