OS-9
Introduction
The FNX6809 combined with the F256 makes a great system for running OS-9/6809. OS-9 was a real-time, embedded operating system created by Microware Systems Corporation. While it was used in many areas of industry, home computer users know it best for its implementation on the Tandy Color Computer sold by Radio Shack
Today, a community effort has led to the creation of NitrOS-9, an open source version of the OS-9 operating system. Throughout this document, I'll refer to NitrOS-9 as OS-9.
A word about platforms
This document assumes you're running on Linux or macOS. If you're using Windows, someone will have to step up and write a document for that platform.
Foenix-specific tools
To get code into the F256, you need FoenixMgr. Download this package and follow the instructions to install it on your machine.
Note, if you're using a Mac, you won't be able to upload code into the F256 due to the driver manufacturer being so behind on updates. I have a Linux VM and use FoenixMgr tools in bridge mode on there. This allows me to run the commands on my Mac and direct them to the Linux VM.
Cross-hosted software
Cross-hosted development is the fastest way to develop code for the F256. For this you need the following:
- lwtools - an assembler/linker package
- ToolShed - a set of tools for creating disk images
- NitrOS-9 - the NitrOS-9 operating system in source form
You can pull these down individually, or better yet, use @strickyak's great CoCo Shelf repository. It has a Makefile which gets all of the above and puts it in a convenient location (note that you'll have to update your shell script of choice to include the locations of the binaries in the PATH environment variable).
Here are the commands to type at the terminal to pull down all the required software:
cd
git clone https://github.com/strickyak/coco-shelf.git
cd coco-shelf
export PATH=$PATH:$HOME/coco-shelf/bin
make mirror-stuff done-lwtools done-cmoc done-toolshed done-nitros9
