    My CB030 has reached some level of maturity. It is a homebrew 24MHz 68030 that works well with 16meg or 64 meg of DRAM, the compact flash interface is solid and I have CP/M68K ported and operating reliably. It is strictly a serial console interface without any video/graphic interface. It does not have a floating point coprocessor. I want to see if I can port NetBSD or FreeBSD to it. To double up the challenge, I'm not a Linux user, but am ready for a long journey. Please tell me where to start.

    NetBSD is a good fit for trying to do a port. You can build a 68k userland and kernel from source on a fast x86 machine using the native build.sh structure. NetBSD does run on 68k macs without an fpu. You can also run it on an emulated Amiga in Winuae. FreeBSD does not run on 68k and modern Debian (unsupported since 4.0) is pretty slow even on beefy Amigas.

    I still have two of the 68030 boards with ISA slots that Ingo Cyliax made at Indiana University.

    There is the start of a simulation for it in MAME

    A daughterboard for your SBC with 8-bit ISA slots might be a fun thing to build, or adding SPI to use a wiznet module.

    A modern Linux has bloated in the 2000's to not even being able to run on a Sun SPARC.
    You would probably have better luck with netBSD
    Hi Al,
    I sent you a PM regarding the CB030 that's currently auctioned on eBay.

    Given that the CB030 looks like an interesting board, but my area is more software, does anybody have any pointers on how to bring NetBSD up on a 68030 Qemu? I thought it would be a good starter for getting NetBSD ported to the CB030 board.
    Thanks, Warren

    Mike McDonald has ported Linux 4.9.156 to CB030. You can find the details here:

    Can anyone please suggesr a light opensource emultor to run relative modern m68k Linux (i.e. Debian) ?
    "Minimal system" is enought, not a full system emulator like HATARI, ARANYM or Snoebill.
    Somethinkg like MUSASHI emulation kernel plus serial plus IDE plus framebuffer wold be enought.
    AFAIK QEMU did not support full m68k emulation (userspace only) but I didn't try it for years...

    MAME has the pieces, but you'll have to put together your own driver.
    You also don't say which 68K, i'm assuming 68030

    I managed to get Debian 10.0 running on qemu-system-m68k by mostly following the instructions at https://wiki.qemu.org/Documentation/Platforms/m68k.

    Here are my full notes: https://gist.github.com/DoctorWkt/78...6bcdd35dd583ef

    I’ve successfully built recent QEMU git (5.0.50) on MSYS2 under Windows10.
    It boots m68k Linux 4.16.0 (unofficial Debian 10 Sid).
    https://wiki.qemu.org/Documentation/Platforms/m68k
    It emulates Quadra 800 with 68040 CPU (1Gb RAM and about 300MHz on my i3 machine)

  10. Default

    m68k Linux 4.16.0 (unofficial Debian 10 Sid).
    Is it something that I can run for e.g. on Amiga Vampire?
    Thanks for answer in advance
