  what you have there is a coding sheet for a GP4. a stored program computer, with drum memory. eventually, the company would call that a 'system design and mechanization report', which would document the math and equations needed to correctly simulate a small part of an aircraft. note the marking "link division of general precision". the computer was made by General Precision, of which the Link aviation company was the biggest customer. i had always been told that Link purchased General Precision, but perhaps it was the other way around. i worked in this industry for about 35 years. this stuff was ancient and forgotten about when I started.
