About the 0-58705

The 0-58705 is a Maxitron Signal Interface created by Reliance Electric. The 0-58705 is a double-sided circuit board. The back panel of the circuit board is covered in hundreds of electron tubes, hundreds of tiny resistors, hundreds of tiny diodes and hundreds of surface mount ceramic capacitors. To learn the exact numbers someone would need a magnifying glass. The back of the board has an edge labeled 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, and 8. The topside of the 0-58705 board also has an impressive amount of components on it as well. The tiny resistors, the tiny diodes, the tiny electron tubes, and the tiny surface mount ceramic capacitors also wrap around to the top side of the board. The circuit boards top side features seven metal brackets of different styles. Four of the metal brackets on the edge on the board has matte black resistors standing upright in them, two on the brackets face each other yet do not touch or have anything in the center. The seventh bracket forms a cage around a bipolar transistor. The bipolar transistor does have a wire connected to it and the opposite end connects to one of the metal brackets that face each other. The card also uses a large microcontroller and thirty-seven other linear circuits. These linear circuits are split between being yellow in color or black in color. There are also over thirty sets of jumper pins around the surface, that are mostly concentrated on the edges of the board.
