The IC3600SGDE1 is a device which is known as a ground detector board. This is a type of printed circuit board or PCB. The IC3600SGDE1 was produced by General Electric or GE to be a part of the Mark I-II series. The Mark I and Mark II were the first two series made for the Mark line. The Mark I was first released in 1969, while the Mark II was released later in 1973.
The IC3600SGDE1 is a large rectangular PCB. Four (4) integrated circuits are placed on the left edge of the IC3600SGDE1. These integrated circuits are rectangular in shape and solid black. Each integrated circuit has a self-contained network of tiny components. This saves space on the surface of the IC3600SGDE1. These integrated circuits are arranged in a vertical line from top to bottom. Four (4) more integrated circuits are attached to the surface of the PCB which are shaped like squares. A long series of large metal prongs is located on the opposite end of the IC3600SGDE1. These large metal prongs can be used to attach more components or other PCBs to the IC3600SGDE1. Placed next to these prongs is a series of capacitors which are solid orange and shaped like squares. There are eight (8) of these capacitors grouped together. Four (4) more of these orange capacitors are placed on the other side of the IC3600SGDE1. In the center of the IC3600SGDE1, there are many light blue resistors which have colored bands. These bands may be blue, red, yellow, or green.
