Isa breakout is an open source PCB design by miselin, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 109 × 79.8 mm, with 9 components from 8 distinct parts.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

The M88 Computer

This repository contains the KiCad project(s) and ROM source code for the M88 computer project. Learn more about the project at https://m88.computer.

The top-level KiCad project is the main KiCad project for the M88's Micro-ATX motherboard.

The isai2c` directory contains a KiCad project for an ISA-to-I2C bridge, designed around readily available parts with only one SMT IC.
