Edsac Replica Project - Rack Layout - Rack R3,M3,M3

By clicking on the racks in the left column, you can see up to three racks side by side. Clicking additional ones discards those in the first displayed rack. Note that if it is necessary to swap chassis to a place already occupied you can use the Bench, which should always have at least one free 'shelf'.
