The computer is programmed with patch cables connecting the components on a switching board.

If an application requires more computing elements than are available on a single machine, two or more THATs can be coupled via dedicated interfaces referred to as MASTER and MINION ports.

[3] The number of computers that can be linked with a MASTER-MINION chain is theoretically unlimited.

[4] Typical use cases in education and theory include the analog modelling of time-based dynamical systems, e.g. mass-spring systems, population dynamics, epidemiological prevalence in the evolution of diseases, mathematical attractors, radioactive decay in nuclear physics, chemical reactions and neuronal bursting.

According to Red Dot "the circuit board-like appearance, versatile use and future-focused conception" are among its outstanding design principles.
