"[...] dropping a crowbar across the DC buss bars"
The 1960s EELM KDF7 was an industrial process control computer. It had an extremely large NiCD battery for power fail orderly shutdown. The battery terminals were two large studs with hexagon nuts to clamp the connection leads. The terminals were sufficiently close together to bridge them with a spanner. Apparently sufficient current would flow to weld the spanner in place.
One sat in the yard rusting for while having been salvaged from a fire. On being turned on again it reported the time of its failure.
