About the 802288-74D
Hardware Tips and Specifications
The 802288-74D is a DRIVE BOARD SIGNAL INTERFACE MAXITRON 9000 SF that was produced by Reliance Electric. The 802288-74D is a large circuit board with many pieces to it. The card features at least thirty-three sets of jumper pins. Some of these pins have slipcovers while others do not. These slip covers can be moved to the sets of pins without them to produce a different effect across the card. The 802288-74D has:
- one extremely tall and wide PCB mount electrolytic capacitor
- two slightly smaller PCB mount electrolytic capacitor
- four cage-like structures that stand on end (two are metal and silver and two are black with a rubbery coating)
- a cage that forms a fence like a perimeter around a bipolar transistor
- a crystal oscillator near this fence
- forty integrated circuits on the surface
- many openings for other integrated circuits of various sizes to be installed
- three yellow and two red radial ceramic capacitors
The card also has two mauve fusible resistors. In between the large components are also a series of multilayer chip ceramic capacitors and SMD surface mounted resistors. To tell the difference there is a marking next to them, “C” for capacitor and “R” for a resistor. The capacitors are also a light color while the resistors are typically black with white markings on the surface. To connect the 802288-74D use the large clip in male terminal on the side and secure it with the screw holes in each corner.
