Shoebill

A Macintosh II emulator that runs A/UX (and A/UX only).

Shoebill is an all-new, BSD-licensed Macintosh II emulator designed from the ground up with the singular goal of running A/UX.

Shoebill requires a Macintosh II, IIx or IIcx ROM, and a disk image with A/UX installed.

Download the latest release, and then see the getting started wiki.

Update (March 29, 2023): About issues/pull requests

I just wanted to say that I appreciate some folks are still using Shoebill and submitting issues and pull requests. I wish I could continue working on this project, but there's a likely conflict of interest, and so I've mostly avoided pushing changes. I apologize for being unable to address the many, many bugs in this repo. (Also for anyone unaware, Qemu is now able now to run A/UX 3.x on its emulated Quadra 800.)

Update (Sept 13, 2015): Shoebill 0.0.5 is available

This will probably be the last release. I won't be able to work on Shoebill going forward (by contractual obligation), so I wanted to race out one last release. Only an OS X binary is available, sorry, and it's very unpolished. But the SDL GUI should still build on linux/windows.

Supports

• A/UX 1.1.1 through 3.1 (and 3.1.1 a little)

Currently Implements

• 68020 CPU (mostly)
• 68881 FPU (mostly)
• 68851 PMMU (just enough to boot A/UX)
• SCSI
• ADB
• PRAM
• Ethernet (via emulated Apple EtherTalk/DP8390 card)
• A NuBus video card with 24-bit depth.

Does not implement (yet)

• Sound
• Floppy
• Serial ports

shoebill crashes when starting Apple HD SC Setup on AUX 3.0.1 Install CD

It seems that every time I open Apple HD SC Setup on the CD it crashes the emulator but if I open it on a copy of AUX 2.0, it opens but does not detect any drive at all.

A/UX 3.0.1: Assertion failed: (fread(scsi.buf, len * 512, 1, dev->f) == 1)

Just being curious I created a A/UX 3.0.1 disk image which I got booted up to INIT: exec /etc/telinit v.

It than crashed with: Assertion failed: (fread(scsi.buf, len * 512, 1, dev->f) == 1), function scsi_buf_set, file scsi.c, line 420.

** BUILD FAILED **


The following build commands failed:
    Ld build/Shoebill.build/Release/Shoebill.build/Objects-normal/x86_64/Shoebill normal x86_64
(1 failure)

Apparently, Xcode 7 introduces a new build setting, “Implicitly Link Objective-C Runtime Support”, or CLANG_LINK_OBJC_RUNTIME, which defaults to YES.

Switching this to NO fixes the issue.

More information:

Take over the Shoebill Project?

Let me start off by saying sad it will be that you won't be able to work on Shoebill going forward. I really like the idea of Shoebill. I guess what I'm trying to say is can I take over the Shoebill project. I'm currently teaching myself how to code with the help of my uncle who is a computer teacher and some friends who code so I have help if I need it. so as I was saying can I take over the Shoebill project since you won't be able to work on Shoebill going forward.

Thanks,

How am I gonna partition disks?

Hey, as I said in the last issue, that Apple HD SC doesn't work, but just one question, Is there any other way I can partition my disks?

Wiki is missing instructions for Windows and Linux

The Wiki (specifically in the Getting Started section) for Shoebill is missing instructions for Windows and Linux... There is even a header for it, but nothing under the header.

Add support for Apple Silicon Macs.

Shoebill doesn't build under M1/M2 Macs.

ShoeBill won't boot from floppy image

I compiled v0.0.5 on Xubuntu 18.04.
I tried to install A/UX 3.0.1 downloaded from winworldpc.

ShoeBill give me the error: partition index 0 has bad magic dada.
The image seems to be working. BasiliskII launch it without problem.

assertion failed when SCSI read returns EOF

Shoebill 0.0.3, A/UX 2.0.7

I'm trying to copy some files in to A/UX by presenting a virtual disk with a 232960-byte tar archive on it. I select the tar archive as the "disk" for SCSI ID 1, then inside the A/UX environment try to read the data from /dev/dsk/c1d0s31. Shoebill crashes, with the following message in the error report:

Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

Application Specific Information:
Assertion failed: (fread(shoe.scsi.buf, len * 512, 1, dev->f) == 1), function scsi_buf_set, file scsi.c, line 357.

The error occurs even when I read less data than is present in the disk file (ie. using dd to explicitly read less data than is present in the disk image file), but does not occur if I pad the file with an extra 10MB of zeros. However if I pad out the disk image file and then read the entire content using dd (with a 512-byte block size) I get the same crash.

It looks like A/UX is issuing reads larger than 512-bytes to the SCSI device, which can try to read past EOF on the disk backing file if it's not a correct multiple of the block size.

mouse is very weird

The only Mac in my house is a Mac Mini I'm using as a server, so I'm using that to use this app via VNC, and when I boot it up and capture the mouse, the mouse in the OS has the acceleration too high and when I switch direction, it's delayed to when it switches direction, it's almost as if the cursor is drunk in the emulator

Crash when doing /etc/fs/ufs/mkfs

First: amazing work you have done with Shoebill. Running A/UX in an emulator is fascinating!

I encountered an error though when doing /etc/fs/ufs/mkfs /dev/rdsk/c1d0s0 1000000. c1d0s0 is an Apple_UNIX_SVR2 partition. Shoebill crashes during or at the end of the super-block creation. Running A/UX 3.0.0.

I'm using Shoebill compiled from sources. Latest commit was at Sat Apr 19 12:12:15 2014 -0400. Let me know if you need more information or testing.
