Modular computer memory circuit board

Claim 1

A computer system having means for protecting electronic circuit boards in a computer system during the addition of circuit boards comprising: a computer power supply having at least two output terminals; a means for limiting current flow in said power supply; a first circuit board having means for locating and connecting additional circuit boards, said first circuit board connecting means having a connection for said power supply first output terminal and at least two adjacent connections, both of said adjacent connections being tied said power supply second output terminal; a second circuit board having means for locating and connecting said second circuit board to said first circuit board, said second circuit board locating and connecting means having at least one connection to receive said power supply first terminal output, said first power supply output terminal connection corresponding to said power supply first terminal connection on said first circuit board, said second circuit board power connection having at least two connections to connect to said power supply second terminal output, said connections being located on either side of said first power supply output terminal connection, and two adjacent connections to connect to said second output terminal, said adjacent power supply second output terminal connections corresponding to said adjacent power supply second output terminal connections on said first circuit board; said connections of said first and second circuit boards being arranged so that the mislocation of said second circuit board in said first circuit board resulting in the connection of system power to system ground, thereby causing the current flow from said power supply to exceed acceptable limits, initiating said limiting means to shut down the supply of power.
