MAME Power Macintosh 6100 boots!

You can always run Leopard in Qemu.
However, would it not be a good idea to provide an empty disk for download?

Best,

Hmm, the lengths I will go to to test stuff .. installing Leopard in order to create a DMG that will hopefully load in DingusPPC so that I can then install 7.1.2 onto it and perhaps make it boot in MAME, even though it's very much a work in progress.. sounds like fun!

I happen to have a functioning 2007 aluminum iMac that originally came with Tiger. I lost the install DVD, and it was upgraded to El Capitan.. but I should be able to download a Leopard or Tiger ISO and then use Disk Utility or the terminal in El Capitan to make a bootable installer, partition the internal drive and then get either of those operating systems running on it again, in order to create the DMG.

This will be an interesting side project in itself.

EDIT - so HFS is deprecated in newer versions of MacOS X. Does anyone have a DMG formatted in HFS (hence readable by DingusPPC) that they would be willing to share? It would not matter what version of MacOS is on it, as long as I can get it to show up on the desktop in Dingus when booting off the 7.1.2 CD - then I can hopefully format and do a fresh install of the OS.

Try this: https://github.com/adespoton/utmconfigs ... y).utm.zip

You'll want the disk image inside the bundle; I've pre-formatted it as a 1GB HFS image with proper partitioning; it works with qemu-system-68k Q800 profile.

However... it's in qcow2 format, so you'll need to convert it to raw using the qemu-img command line tool before you can use it in DingusPPC or MAME.

You could also run it through chdman before using it in MAME if you wanted to -- and MAME also supports a fake NuBus device that can handle a SheepShaver-formatted single HFS partition image, wrapping it with all the stuff needed to boot a real system.

Seems odd to me though that Disk Jockey-formatted images wouldn't work. It must be installing the 68k SCSI driver instead of the PPC one?

Perhaps. I tried both the Windows and macOS versions of Disk Jockey, with the same result: DingusPPC recognizes the image in the terminal, but upon boot, the message "This disk is damaged: Do you want to initialize it?" appears. Clicking initialize will result in the freeze up I previously mentioned. The disk was created with the 'BlueSCSI' pre-set.

This is an empty 1GB hard disk image (raw format - no compression or headers - works with DingusPPC and SheepShaver) with Mac OS 9 drivers and HFS formatted partition.

created using the method I described previously using Intel Mac OS X Leopard 10.5.8.

Thanks for the disk images, that has sped up the testing process.

This is what I can confirm so far:

1. The blank DMG above works fine in DingusPPC with System 7.5.5 installed onto it. So I know the image is OK.
2. The System 7.1.2 ISO (691-0187-A,Power Macintosh 6100-60-60AV, 7100-66-66AV, and 8100-80-80AV. SSW v7.1.2 (CD) SHA-1: 66D8ECDF5EB9B42F2467E03614541E43986C78D1) boots successfully in Dingus PPC if no HDD is specified in the launch parameters.
3. If I then add the blank DMG to the launch parameters, the CD image boots up to the point of the QuickTime extension loading, and then I just get a blank grey screen with apparent freeze up (which prevents me from installing System 7.1.2 onto the DMG using DingusPPC).
4. Instead, I installed 7.1.2 onto the DMG using SheepShaver. Booting it up in DingusPPC gets to the "Welcome to Macintosh" window and then freezes up.
5. I transferred the contents of the DMG (System 7.1.2) onto an HDA image that I know to be working properly in MAME. Booting that takes me back to the same Error Type 11.

So in summary, DingusPPC will boot the 7.1.2 CD (for the 6100/60) but only if no HD is specified alongside it in the launch command. DingusPPC will not boot a DMG with the same system installed on it. In MAME, both the CD and any HDA image with the system from that CD installed onto it will bring up the Error Type 11.

The takeaway is that neither DingusPPC or MAME appears to be compatible with the specific version of 7.1.2 released for the PowerMacs. If a hybrid 68k version works, I am yet to successfully locate it.
