The strangest thing was a control system made out of logic blocks (kinda like Lego blocks) with each block having an OR-gate, an AND-gate, or a timer. A nightmare to troubleshoot !

Were these MTE (I think) blocks that stacked on top of each other with screw clamp connectors sprouting all around, about the size of a cigarette packet. They stacked on breakable metal rods, if one failed in the middle of the stack then you had to disconnect everything above and slide them off to change hteone that had failed. I hated those.
