Qemu-system-m68k-Win64 to run Mac OS 7-8 / AUX3.x / NetBSD

[emendelson]

It this a plugin replacement for the previous version? (In other words, can I simply copy into that AUXrunner app I threw together a while ago?)

[Cat_7]

Yes, AFAIK it can replace the build your current bundle. As noted: the tablet driver cannot be used in A/UX

Silly me - I didn't notice that this was a Windows build even though it says "Win64" up there in the heading... I'll wait for a new macOS build...

[Cat_7]

Building for macOS is getting ever more difficult, I'll see what I can come up with.
It also seems time to find some affordable m1 mac mini..

[emendelson]

Don't feel any pressure from me about this! You've already done heroic work for the rest of us!

And yes, an ARM Mac will be surprisingly fast and reliable. Enjoy!

And thanks again...

Hi!, why when trying to initialize the drive, it does took long to do so?

qemu-system-m68k.exe ^
-M q800 ^
-m 128 ^
-display sdl ^
-bios Quadra800.rom ^
-drive file=pram-macos.img,format=raw,if=mtd ^
-device scsi-hd,scsi-id=0,drive=hd0 ^
-drive file=MacOS761.img,media=disk,format=raw,if=none,id=hd0 ^
-device scsi-cd,scsi-id=3,drive=cd0 ^
-drive file=MacOS761.iso,media=cdrom,if=none,id=cd0

here is the bat

Hi!, how do i mount a dsk file into this emulator? what format are allowed for floppy format?

[psh]

Looks like this version of QEMU is glitched with bug of last version as QEMU PPC (Command key dont work properly)

Hi, Mr. Cat_7

The link is pointing to the PPC system one. Please fix it.

Thanks! See ya!

[Cat_7]

Fixed!

Hello. When trying to setup my mac os 7.6.1, the initialization process took quite a long time. why is that?

Hello. When trying to setup my mac os 7.6.1, the initialization process took quite a long time. why is that?

This seems to happen with every emulator I've tried. Possibly the initializing software has delays built-in so that it works correctly on real hardware. But that's just a guess.

but it took long than it should be

btw i use the drive setup tool

btw i use the drive setup tool

I just used Drive Setup to take a 1GB image and format it into four HFS partitions. Took a total of 3 seconds on my M1. Most of that time was spent redrawing things on the screen; I think the actual process happened in under a second.

So is the delay specific to Win64?

well that took me like around 45 minutes-1 hour mark for me

anyway, how do i able to have the basilisk ii/sheepshaver file image be usable on qemu m68k?

You don't, directly. BII and SS use a file containing only the HFS+ partition; QEMU, emulating an actual machine, requires an actual drive image with the driver partition.

You can mount a BII or SS image inside a booted OS in QEMU using Disk Copy or the like, but you can't add them to the list of volumes in QEMU and expect them to work.

Conversely, you could take a proper image formatted in QEMU and mount it in BII or SS and copy the files over, or use Disk Jockey to convert between the formats.

Couldn’t we use diskutil with a byte offset and -nomount to link only the HFS+ partition of a QEMU image to, e. g. /dev/qemu_img_offset ?
(See https://unfinishedbitness.info/2017/02/ ... ge-mounts/ )

A script could calculate the byte offset from the QEMU image and use it to run the diskutil command. /dev/qemu_img_offset can then be added as a drive to SS.

ok, now i need to solve this problem asap. Now the pram image is corrupted, making me unable to boot into my mac hd

[psh]

Hi, i think i have a problem. right now. for some reason, my emulator seems to unable boot to the OS. The pram image was szeems to be corrupted. I tried many ways to do it, including remaking the whole pram image several times. But, nothing works

[RonsCompVids]

Is there a release yet that supports the Command key? On Windows, if you get locked into a situation where you need to CMD + . something to abort, you're basically softlocked.

[RonsCompVids]

So no?

[Cat_7]

Hi,

The Command and Option keys are reversed but the Windows menu does not show up when the mouse is captured in the Qemu window and you press the Windows (Command) key.
So you can type Command + .

Or does that not work in your Qemu-system-m68k?
