The ZO161 module is one of the most simple modules of the Hitachi 240 analog computer. It contains just passive electronic elements like precision resistors and some precision capacitors.

The precision capacitors can be seen on the left hand side of the picture on the left while the resistors are mounted directly behind the module front plate.

The picture on the right shows a closeup of the precision resistors and the module front plate.
