m68k development information[5]
Nelson H. F. Beebe from the University of Utah writes on the Debian m68k mailing list[1]:
> I'm pleased to report that a build of TeX Live 2023 on Debian 12 68K (QEMU 7.0.0 emulation thereof) succeeded here last week, and binaries are available at links from
> => https://www.math.utah.edu/pub/texlive-utah/ https://www.math.utah.edu/pub/texlive-utah/
The DVD production for TeX Live 2023 (a distribution of the TeX typesetting system) has been started.
/(news reported by Adrian Glaubitz)/
The upcoming Linux Kernel 6.3 will support the "seccomp[1]" security feature for the m68k cpu architecture. With "seccomp", a developer or administror can limit the systemcalls a Linux application can use to communicate with the Linux Kernel. This allows for a tighter privilege separation of processes, as processes can be restricted to just a part of the Kernel function (filesystem, process management, network communication etc).
For full "seccomp" support in m68k Linux systems, the libsecomp library needs support for m68k systems as well - a patch has already been submitted by Adrian Glaubitz: => https://github.com/seccomp/libseccomp/pull/397 https://github.com/seccomp/libseccomp/pull/397
At https://asm-editor.specy.app/[1] you can find an editor, assembler and (simple) m68k emulator that let's you code assembly projects in the browser. Maybe this develops into something like https://8bitworkshop.com[2] is for 8bit machines.

> There is a new linker called "Mold" [1] that is being developed by Rui Ueyama, one of the core developers of LLVM [2].
> Rui has said in a discussion on Github that he is accepting donations [3] and that he is willing to add m68k support to Mold if we can raise $1000.
> I have already started a crowdfunding campaign in the German a1k.org Amiga forum and we have already collected $250 [4]. If we can get another $750, Rui will start working on m68k in Mold.
> So, if anyone is willing to support this effort, please go his sponsoring site [5] and make a one-time donation. If you have made a donation, please let me (Adrian) or Rui know so that we can track who has sent money to support the m68k backend.

The advanced Linux distribution Gentoo[1] has been reborn, current Stage 3 tar-balls are available at https://www.gentoo.org/downloads/[2] (select `m68k'). Gentoo is a Linux distribution aimed at experienced Linux user that like to have full control over their Linux system. This new Gentoo Linux port has been made possible by the new m68k system support in Qemu (with larger memory support) that permits easier building of binary packages for m68k architectures.
Thanks to Adrian Glaubitzs work the m68k backend for the RUST programming language[1] is now making it's way into the official repository as a Tier 3 supported architecture. As more and more linux software (Firefox, libsvg, topgrade, ...) and parts of the linux-kernel are written in Rust, this is a very good development as the m68k machines will be able to enjoy modern and secure applications:
Add m68k-unknown-linux-gnu as new Tier 3 backend[2]
Add initial support for m68k[3]

In this chat we've discussed the "ClangBuildLinux" (https://clangbuiltlinux.github.io[1]) Project. This project builds the Linux-Kernel with the LLVM compiler infrastructure. Now that Min-Yih Hsu has created the m68k backend for LLVM, it might be possible to compile the Linux-Kernel for m68k targets with the modern LLVM compiler infrastructure.
Nick Desaulniers explains the "ClangBuildLinux" Project, the reasons for building the Linux Kernel with LLVM, issues found in the Linux-Kernel through the LLVM code checker. Min-Yih Hsu joined in the chat to give information on the LLVM m68k backend.

This video explains and demonstrates the QEMU user mode and how to setup an Linux m68k development environment that can seamlessly be used from an amd64 host.
With this environment, it is possible to write scripts that execute a mix of native (amd64) and emulated (m68k) commands. It is also possible to start the m68k environment inside a Linux container using systemd-nspawn.
QEMU user mode is a great addition to every cross development toolbox.

Laurent Vivier talks about the existing QEMU Quadra 800 emulation and the linux-user mode. He does explain what are their limitations are, and then what a pure virtual machine can improve. He gives a demo that shows what the machine can do and how to use it. The demo shows live migration between Qemu instances, 9P file sharing between host and Qemu and running Linux m68k in Qemu with a XFCE GUI.

Joshua Stein started a video series on development on and for MacOS system 6:
> I've been writing an IMAP client for and on my Mac 512Ke over the past many weeks. Taking inspiration from Andreas Kling's excellent YouTube videos documenting his development of the Serenity operating system, I thought I'd start screencasting some of my work.
> This video is the first of hopefully many and presents a quick introduction to System 6, HFS resource forks, THINK C 5.0, and a look at some of the progress of my IMAP client so far.

Cameron Kaiser has released a gopher client for AMOS OS on Alpha Micro by hacking its TCP client suite: => https://oldvcr.blogspot.com/2020/09/hacking-gopher-client-into-alpha-micro.html https://oldvcr.blogspot.com/2020/09/hacking-gopher-client-into-alpha-micro.html
The Alpha Micro machines were based on various 68K CPUs but notable that they were multiuser business "mini minis" and actually run the 68K in little-endian mode for compatibility with their previous architecture's data files.

Charlie wrote: you can link together 68k ELF objects to Atari PRG with `vlink' . It's the linker that goes with vbcc & vasm (not FLOSS but you get the source). It works in practice too, I use that combination in Free Pascal for TOS support. Using ELF objects have several advantages over a.out objects, like named sections, which allows section garbage collection linking time. => http://sun.hasenbraten.de/vlink/ http://sun.hasenbraten.de/vlink/

after almost 20 years of development the EmuTOS project reached the version number 1.0. EmuTOS is a Free operating system for computers based on Motorola 680x0 or ColdFire microprocessors. It features functionality similar to TOS, which powered the Atari ST and its successors between 1985 and 1994.
Major changes:
BIOS: Add keyboard mapping for Spanish keyboard
BIOS: Change Spanish character set to Atari ASCII, like Atari TOS
BIOS: Improve joystick compatibility with Atari TOS
EmuDesk: Implement "Search"/"Cycle windows"/"Select all items" in File menu
EmuDesk: Implement "Size to Fit" in View menu
EmuDesk: Implement "Cache" in Options menu
EmuDesk: Add user-modifiable shortcuts for desktop menu items
VDI: Add support for Atari GDOS
VDI: Fix spacing and positioning of outlined text
VDI: Improve text output quality for special effects
VDI: Underline text within character cell if possible, like Atari TOS
General: Add Polish language support
General: Generate language-specific ROMs for PAK 68/3 hardware

Recording from the m68k.info chat on 21st August 2020:
neozeed[1] had success in running the C-Compiler of AT&T Unix on the FreeBee[2] Emulator (emulating a AT&T 3B1 machine, patched version of the emulator https://github.com/shadyjesse/freebee[3]). Now it is possible to compile new software for these interesting old Unix systems: => https://virtuallyfun.com/wordpress/2020/08/29/thanks-to-shadyjesse-philpems-freebee-can-now-run-the-c-compiler/ https://virtuallyfun.com/wordpress/2020/08/29/thanks-to-shadyjesse-philpems-freebee-can-now-run-the-c-compiler/
The ZZ9000[1] graphics card from MNT (revision R-1 and R-2) has a design error that shorts the 1V8 and 3V3 supply voltage rails of the ZYNQ module, causing the ZYNQ module to overhead.
In his blog article "The first cut is the deepest![2]", Stefan Reinauer explains how he found and fixed the issue.
MNT has published a document on about the fix[3].
In addition, the MNT ZZ9000 Firmware 1.7.0 Beta 2[4] is now available along with a new version of ZZTop[5] (AmigaOS tool for ZZ9000 diagnostics).
Francois Revol has re-started work on his port of the HaikuOS[1] to the Motorola 68000 architecture. Recent progress https://m.g3l.org/@mmu_man/104558619892698374[2]. Older status reports on https://www.haiku-os.org/tags/m68k/[3]
Not new, but rediscovered in August: Rob Braun has some interesting notes on booting NetBSD/m68k on a Mac Centris 650. His Webpage also has some interesting system tools for classic MacOS.

John Paul Adrian Glaubitz reports that the m68k backend for LLVM has been finished. It has not been merged upstream yet (that will take some time), but it should be usable now. Adrian is currently test-building it on Debian/m68k and it is asking for help finding issues: https://lists.debian.org/debian-68k/2020/06/msg00029.html[1]
