Hardware simulation logic circuit bench

A reconfigurable hardware logic circuit simulator bench, comprising

• a frame;
• a holding slot, supported by the frame and extending along an axis from a holding slot base end and comprising guide surfaces that extend parallel to the axis;
• a slot power connector, supported by the frame, and arranged at the holding slot base end;
• a plurality of slot-supported circuit board devices, arranged in the holding slot and moveably supported by the guide surfaces, one of the slot-supported circuit board devices being a slot supported first circuit board device, and another of the slot-supported circuit board devices being a slot supported second circuit board device, each slot-supported circuit board device comprising:
• a substrate extending a width along the axis from a first side edge to a second side edge,
• a guide engagement structure secured to the substrate and configured to moveably engage the guide surfaces, and
• a power rail segment, supported by the substrate and comprising:
• a power rail conductor extending from a first end proximal the first side edge to a second end proximal the second side edge,
• a first side edge rail connector coupled to the first end, and
• a second side edge rail connector coupled to the second end, wherein:
• the slot-supported first circuit board device is adjacent the slot power connector,
• the slot-supported second circuit board device is adjacent the slot-supported first circuit board device,
• the first side edge rail connector of the slot-supported first circuit board device is aligned with and reversibly coupled to the slot power rail connector, and
• the second side edge rail connector of the slot-supported first circuit board device is aligned with and reversibly coupled to the first side edge rail connector of the slot-supported second circuit board device.
