This is the discrete time version of a Harmonic Oscillator, an energy conserving differential equation. The introduction of nonlinearity results in the complex behaviour.

BTW, here's Minsky's own application, known as the "Minskytron":

(You may set 3-bit wide bit-shift parameters by the switches at the bottom of the screen in groups of 3, one each for scaling x and y parameters of each of the 3 generators/oscillators. There are also a few presets in the menu at the top to select from. Mind that patterns aren't exactly stable for the limited 18-bit word precision of the PDP-1.)

For those interested in the workings, there's a schematic in the description and a link to the annotated source code.
