Fuzix OS on BSD

https://gyazo.com/26887c1f78fa2deb8b088e7be05ecf28

はじめに

色々なCPUで動くFuzix OSが、なぜか、むとうのまわりで流行っています

浜松Fuzixユーザーグループ

エミュレーターだけではなく、たくさんの実機で動かしている

https://gyazo.com/d3f5719034d7fadc5b444864fc2b84a8

BSD界隈: 以下の動画参照

omron LUNAのサブCPU(Z80)で動かすために作業している

fuzix and NetBSD/lunaの同時実行!!

ちょっくらFreeBSD/aarch64(Pinebook)なんかで試してみました

Fuzix OSとは?

2024/08/01現在のバージョンは0.5

色々な8bit/16bitのCPUで動くUnixのようなもの

FuzixOS: Because Small Is Beautiful

めちゃくちゃ多くの対応プラットフォーム(詳しくは、公式トップページを確認)

例: Z80(MSX), ESP8266, 6800, 8086, ARM(RP2040), PDP11, ...

ライセンスは、GPL v2 + LGPL(ライブラリ部分)

SYS3 - SYS5.x + 少しのPOSIX対応

BCPL, CC, asm, Forthなどもある

Raspberry Pi PicoでFuzix OS

ちょこっと試してみたい場合に便利

バージョンは0.3.1とちょっと古い

Pico以外のハードウエア(SDなど)は不要

code:shell

% sudo cu -l /dev/cu.usbmodem0000000000001 -s 115200

Connected.

Current time is 23:37:29

Enter new time: 14:00:00

Fuzix on RC2014 with RomWBW

以下の手順で、とりあえず動く

作業ディレクトリの作成

code:shell

% mkdir work

% cd work

ROMの準備: 最新のv3.4.1では動かせなかった

code:shell

% mkdir roms

% cd roms

% unzip ../RomWBW-v3.0.1-Package.zip

(snip)

% cd ..

ディスクイメージファイルの準備

ダウンロードがとても遅いので気長に待って…

code:shell

% mkdir rc2014

% mv emu-ide.img rc2014/

code:shell

気になったこと

Wiznet w5100をprobeしているので、Ethernetが使える?

$ TERM=xterm vi

おまけ: Fuzix以外で遊ぶ

後の説明で、イメージがbuildできたのはこいつ用です

code:shell

$ mkdir sbcv2

$ cd sbcv2/

$ cd ../

$ ../rbcv2 -r roms/Binary/SBC_std.rom -i sbcv2/emu-ide.img

Fuzixを自分で作る

なんか、ドキュメントがほとんどなく、Web検索しても古いものが多くて、めんどくさかったです
