Serial In Parallel Out digital Shift register.

SIPO is a 6hp Serial in parallel out shift reigster.

Designed to transform gates and triggers into evolving patterns. By passing gate inputs through a series of logic stages, the Shift Register creates pseudo-random or repeatable rhythmic sequences—ideal for clocks, gates, and stepped voltages.

What is a Shift Register?
A shift register is a digital logic circuit that passes input data (typically high or low logic signals) through a chain of memory cells, shifting the data with each clock pulse. Each output stage reflects the state of a previous stage in time.
