To satisfy the need for an easily programmable portable analog computer, a compact, punched-card programmable computer is herein described. This compact computer may be programmed three different ways: 1. using conventional patch cords; 2. using mechanical switches; and 3. using a single punched card. The top panel of the cabinet is a combination patching, switching and electronic module board and includes all of the computing components, toggle switches, mode control switch, power switch, voltmeters and computing module diagrams. The mode control switch enables the user to perform "reset", "hold" and "compute" operations. The voltmeters enable input and output voltages of a programmed problem to be measured simultaneously. Switches or relays enable the user to inter-connect computing components, while jacks on the board permit patching other components of a problem, previously programmed on a sheet, for which switches or relays have not been provided. Program symbols appear on covers over the computing modules identical or similar to the ones appearing on a programmed sheet.
