12-bits old fashioned homebrew Minicomputer

Introduction


HER/12 is a hobbyist project which goal is to design and build a mini-computer using 1970's technologies. Built from discrete SSI and MSI integrated circuits rather than VLSI microprocessor, the machine is meant to taste old and serve well for the years to come.

Architecture

This section describes the computer's hardware in a generic, introductory way.
The Instructions Set Architecture (ISA) is covered in details.

Electronics

CPU block diagram, theory of operation, time diagrams and schematics are found in this section.

Peripherals

Operation

How to operate the computer and its peripherals.

Software

Specs

This section contains specifications developed ahead of time as an attempt to develop a solid ground prior to actual design and implementation.
