MAME Power Macintosh 6100 boots!

Post by kikyoulinux »

Tried to emulate Power Macintosh 6100 with MAME 0.239.
The pre-installed System 7.6.1 CHD image does not support PowerPC Macs. Floppy images has to be set read only or you'll be greeted with "Fatal error: floppy dma write". System 7.1.2 and System 7.5 floppies throw a boom on startup. Luckily, System 7.6 floppy boots. But the mouse pointer does not move and the keyboard may not work too.

Pre-installed? MAME doesn't have any pre-installed CHDs. Also, this should probably not be in the 68k area of the forums. Good to know it boots though! Possibly with some finangling it can get the correct HID hardware too. My big question though is: can it run Mac OS 8.5-8.6? Because that's the current gap in qemu between qemu-system-m68k and qemu-system-ppc, and whatever they did to get it booting may be transferrable to qemu :)

I moved the topic to this forum.

MAME provides some pre-installed System 6 and System 7 images on this wiki page.

Perhaps they are made for 68K machines.

MAME-labeled "imperfect" machines like Mac IIvx works. Virtual memory works. But FPU emulation isn't very accurate and causes some scroll bar issues.

The non-working machine Quadra 700 doesn't boot from SCSI hard drive or CD. MAME provides an emulated nubus device "image" to access those images used by Mini vMac. Currently, the emulated Quadra 700 only boots from the nubus image device.

I managed to boot the system with a customized floppy image that contained a System suitcase from System 7.6 floppy and Finder from System 7.1.2 floppy.
Keyboard and mouse do not work currently.
