README
README.mdMUTIF09 Project
MUTIF09 (or shortly MUTIF) project is my hobby project for developent of tiny homebrew computers and their add-on/expansion boards (e.g. Arithmetic coprocessor and I/O expansion board) simple enough for building and maintenance, focusing on around 1980s-era microprocessors (e.g. Motorola's MC6809, Harris' HD-6120) just for fun.
FAQ
-
When are updates available?
Updates are available when they are released.
-
What does MUTIF mean?
MUTIF is an anagram of two amaterur radio call signs of my own (suffix only).
-
How to assemble these things? / Where is the assembly manual?
Refer to the schematic(s), order the PCB(s), collect parts required, populate the parts on the PCB just as you did in your other DIY electronics project. Knowledge of basic soldering techniques is also required. Remember to get your PC ready for USB-TTL serial cable installed.
Like other open source projects, documents, sample programs and ohter design materials contained in this repository are provided "as is" without warranty.
As for assembly manual(s), you can download the document(s) (e.g. "Technical memorandum on MUTIF09 6809 Single Board Computer" ) (for a fee) from BOOTH online store. Note: these booklet(s) are written in Japanese only.
https://m-nihombashi.booth.pm/
Or, you can get a copy at doujinshi sales exhibitions (e.g. Comic Maket, TechBookFest, Micom-Infinite PRO-68K).
I encourage you to get your copy of the booklet (if necessary) at the online store ( https://m-nihombashi.booth.pm/ ) due to the COVID-19 situation.

Questions
How big is the IOExpansion PCB?
It measures 155 × 114 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IOExpansion use?
198 parts, built around the ADUM1250AR, MCP809-315I/TT, MCP809-450I/TT and MCP810-450I/TT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the IOExpansion KiCad files?
From the ja1umi/MUTIF09Project repository on GitHub, at the commit this page was made from: the board is IOExpansion/IOExpansion/IOExpansion.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the IOExpansion design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
