The Heathkit/Zenith MicroComputer Learning System model ET-3400 was a very popular item designed to teach principles of computers and programming at universities in the 1970s, and to educate the students of internal computer hardware and software components by self-assembly and programming the machine in pure Hexadecimal language.
It was delivered in assembled or kit form. It also featured a prototype area and could be used as a design aid for developing special interface circuitry with common 6820 parallel interface or 6850 asynchronous chips.
Several software in ROM were also available, among them an Assembler and a Tiny BASIC.
