The B4 is a modular computer processor made to help students explore the fundamental operation of computers. It has been designed from the ground up to support students who are studying the new Australian Curriculum: Digital Technologies.

The B4 consists of 11 computing modules that represent core functions of a computer, such as a program counter, adder, inverter, memory, latch, etc. With these, students perform experiments in which they learn about binary numbers, binary addition, memory, etc. These experiments lead to increasingly sophisticated hardware and software arrangements that result in a simple yet functional computer. The B4 operates at human speed, allowing students to easily follow with their own eyes how data flows between each of the modules.
