I don't see any text explaining how this works beyond:<p>> The Electronic storm surge model is a depth-integrated single-layer two-dimensional electronic model based on hydrodynamic equations used to examine tidal surges, comprising three main units; a unit holding the input and output devices (Advance Instruments OS-240 oscilloscope, Commodore CBM 8032 Computer and Commodore 2031 5¼" floppy disk drive, and another two units (connected and wired together in a V formation) forming the mesh framework of the machine.<p>and there are not enough pictures for me to understand. My guess is that this is an analog computer which uses voltages in circuits to model the differential equations of the atmosphere pressuress? And do they divide up areas of the atmosphere into each cell or something?
