Gopher Client for the AMOS OS running on Alpha Micro machines

  • 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
  • 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. General information: http://ampm.floodgap.com/ (hosted on an Alpha Micro Eagle 300, a 1994 system with a 68EC030)

EmuTOS Release 1.0   Atari Amiga

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

AT&T Unix on m68k Hardware emulator   Unix Retro

neozeed had success in running the C-Compiler of AT&T Unix on the FreeBee Emulator (emulating a AT&T 3B1 machine, patched version of the emulator https://github.com/shadyjesse/freebee). 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/

Hardware fix for the ZZ9000 graphics card and new firmware and tools   Amiga

The ZZ9000 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!", Stefan Reinauer explains how he found and fixed the issue.

MNT has published a document on about the fix.

In addition, the MNT ZZ9000 Firmware 1.7.0 Beta 2 is now available along with a new version of ZZTop (AmigaOS tool for ZZ9000 diagnostics).

Haiku on m68k   Haiku NeXT

Francois Revol has re-started work on his port of the HaikuOS to the Motorola 68000 architecture. Recent progress https://m.g3l.org/@mmu_man/104558619892698374. Older status reports on https://www.haiku-os.org/tags/m68k/

NetBSD on Mac68K   NetBSD Mac68K

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.

m68k backend for LLVM has been finished   LLVM Debian Linux

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
