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

Even up to four!

I was wondering how you are doing with the multi-display setup.

Best,
Cat_7

Apologies for silence. I haven't tried it yet, because I don't have a second monitor here to use with my MacBook Air. At some point, I'll borrow the second monitor that my wife is using, but that will have to wait until she finishes her current project. I'll shout as soon as I have anything to report.

[Cat_7]

You don't need a second monitor. You can have up to four Mac OS windows on one monitor
However, if you have a second monitor already extending your macOS host desktop you can drag one or more Mac OS window to the second monitor.

Some progress. Here is the script I use:

Code: Select all

#!/bin/bash
cd "$(dirname "$0")"

./qemu-system-m68k-qfb \
-M q800,fb=none \
-bios Quadra800.rom \
-device nubus-qfb,width=600,height=480,depth=16 \
-device nubus-qfb,width=600,height=480,depth=16 \
-display sdl \
-nic user,model=dp83932,mac=08:00:07:12:34:56,hostfwd=tcp::2121-:21 \
-drive file=pram-macos-qfb.img,format=raw,if=mtd \
-device scsi-hd,scsi-id=0,drive=hd0 \
-drive file=root.img,media=disk,format=raw,if=none,id=hd0  \
-device scsi-hd,scsi-id=2,drive=hd1 \
-drive file=opt.img,media=disk,format=raw,if=none,id=hd1 

It starts up A/UX with two windows, but one has a mesage "kernel error" followed by a few lines of hex digits etc., and the other is blank.

If I'm doing something obvious wrong, then I'll keep trying. Otherwise I wonder if I did something in my initial setup that makes this not work.

[Cat_7]

Your command line is fine. This is a pram issue.
Here are two pram files: one empty (to keep as spare), one that works with A/UX at my place: https://surfdrive.surf.nl/files/index.p ... t/download

Aha! Thank you! I would never have guessed this. Now - this should be obvious to me, but it isn't: How do I get a window to open in the second screen???

[Cat_7]

First check whether you have the windows arranged correctly. You can use the Monitors control panel to check. But take care, the Mac OS 701-AUX control panel is not the most stable. (the ones included in Mac OS 7.5 up to 8.1 do better).
Put both windows side by side and drag applications or icons to the other screen. It should be a seamless experience.

Please note: only when running with -display sdl you get to see two screens at boot. cocoa or gtk require you to select the second screen from their window menus.

Well, this is strange. I tried it twice, and posted an image of the two monitors side by side, with the numbers 1 and 2 identifying them correctly. But I couldn't drag from one to the other.

But now I tried it a third time, and it works perfectly! Thank you for your patience with this.

And while I'm asking: I see that the command line in the download doesn't have the /m-128 option that was in my original. I think I see that 128MB is the default setting, so you don't need that option. But is there any advantage in setting it higher or lower?

Again thanks. I'll post this setup in the next few days.

[Cat_7]

Max ram for the quadra 800 seems to be 132 Mb, so I would not go any higher.
The second screen can indeed be unresponsive until you use the monitors control panel.

And, as you said, the Monitors control panel is unstable. When I tried to change the color seting from millions of grays (I don't remember setting it that way, but that's what it was) to 256 colors, the system crashed. Working correctly now.

It occurs to me that it shouldn't be hard to combine the multiple-screens setup and the single-screen setup in a single AppleScript app so the user could choose between them (maybe by changing the name of the app). I'll try to find some time to put that together in the next week or two.

[emendelson]

I've now updated my page with a new download and an explanation of how to run the two-screen option:

[Cat_7]

Works as advertised!

I'd like to suggest a small change to your download page.
It would be better to warn users that the shutdown can take some time and that they should wait to close the Qemu window until the "safe to shut down" message appears.

Cat_7

[emendelson]

Done!

[Cat_7]

I hope you didn't replicate both language errors in the earlier message (now fixed)

Probably I did! What was the error so that I can fix it?

[Cat_7]

No, you didn't. It said "save to shutdown"

If there is anything that needs saving it is my language skill

Somehow I doubt that. Although my day job requires me to talk about books written in many languages, whenever I'm in the Netherlands, I feel like a monoglot barbarian.

Code: Select all

qemu-system-m68k: -drive file=pram.img,format=raw,media=mtd: 'mtd' invalid media

Any suggestions?

[Cat_7]

Yes,

-drive file=pram.img,format=raw,if=mtd
