This metal cartridge contains wire used to enter programs on the SEAC computer. A paper ring atop the cartridge lists programs on it. The object is mounted on a wooden backing with a metal plaque that describes the contents of the cartridge.
A wire cartridge was used to enter data onto the SEAC from at least 1954. The machine went out of service in 1964. This is not the first version of the demonstration cartridge. Hence the date assigned.
